2: Upgrading to CAPA 5.1
3:
4:
5: --------------------------------------------------------------------------------
6:
7: READ ALL INSTRUCTIONS BEFORE PRECEDING WITH THE INSTALLATION.
8:
9: Please go to http://capa.msu.edu/mailman and subscribe to the CAPA Announce
10: email list. Anyone interested in receiving CAPA updates and announcements
11: can add himself or herself to the list. Please notify all instructors and
12: technical staff that will work with CAPA about adding themselves to the list.
13:
14: The following installation instructions assume that whoever is upgrading
15: the CAPA system already has some knowledge of their operating system and
16: is familiar with Unix commands such as the following: cd, chown, chmod and
17: setting permissions, compress/uncompress, cp, ln, lpr, ls, mkdir, pwd, rm,
18: su, tar, and the vi editor.
19:
20: In order to complete the installation, you will need to have Perl,
21: Ghostscript, TeTex, and a webserver (e.g. Apache) installed on your machine
22: (all of which can be obtained for free). You should know where those
23: applications are located and where the web server's configuration files are
24: located (particularly srm.conf). You should also be familiar with killing
25: and restarting your web daemon.
26:
27: You will notice lists of files in these instructions to compare your
28: permissions with. Depending on your operating system, many of your file
29: sizes may differ with the ones given in these instructions. Please do
30: not be concerned by this.
31:
32: --------------------------------------------------------------------------------
33:
34: SETTING UP THE INSTRUCTOR INTERFACE AND OPTIONAL TELNET STUDENT INTERFACE
35:
36: You have the option to install the telnet version of the CAPA interface.
37: It responds much quicker than the web, especially with a slow modem. If
38: you decide not to enable this feature then skip steps 5 and 6.
39:
40: Please note that in the following instructions, it is assumed that the
41: teacher directory is in /home. This may not be the case with your machine
42: (e.g. /usr/users, /home2, etc.). You may want to make note of this as you
43: read through these instructions prior to installation.
44:
45: 1.) Become root and copy or move the DIST51 directory to the teacher home
46: directory. Recursively change the ownership of the DIST51 directory to
47: teacher with group membership cai.
48:
49: >chown -R teacher:cai DIST51
50:
51: 2.) We first need to link up the binaries to use the instructor
52: interface of CAPA. Login as root. Change directory to /usr/local/bin
53: (or /usr/bin, or whatever will be the default in your users "path").
54: Remove all the old links to the CAPA 5.0 binaries and then symbolically
55: link the 5.1 binaries contained with the distribution by entering the
56: following commands:
57:
58: > cd /usr/local/bin
59: > ln -s /home/teacher/DIST51/LinkToBin/quizzer .
60: > ln -s /home/teacher/DIST51/LinkToBin/grader .
61: > ln -s /home/teacher/DIST51/LinkToBin/manager .
62: > ln -s /home/teacher/DIST51/LinkToBin/qzparse .
63: > ln -s /home/teacher/DIST51/LinkToBin/allcapaid .
64: > ln -s /home/teacher/DIST51/LinkToBin/answers .
65:
66: 3.) Check that all of the binaries in /home/teacher/DIST51/LinkToBin
67: have executable permissions as shown below:
68:
69: >cd /home teacher/DIST51/LinkToBin
70: >ls -l
71: -rwxr-xr-x 1 teacher cai 485095 Jul 17 14:35 allcapaid
72: -rwxr-xr-x 1 teacher cai 505454 Jul 17 14:35 answers
73: -rwxr-xr-x 1 teacher cai 2126685 Jul 17 14:35 grader
74: -rwxr-xr-x 1 teacher cai 2267429 Jul 17 14:35 manager
75: -rwxr-xr-x 1 teacher cai 2191991 Jul 17 14:35 quizzer
76: -rwxr-xr-x 1 teacher cai 488366 Jul 17 14:35 qzparse
77:
78: 4.) Now link up the demonstration library in the root directory. To do this,
79: login as root, change to the root directory (cd /), remove the old demolibrary
80: link (rm demolibrary), and enter:
81:
82: > ln -s /home/teacher/DIST51/demolibrary demolibrary
83:
84: Check that the demolibrary in the DIST51 folder is owned by "teacher" and
85: has group membership "cai".
86:
87: 5.) *SKIP THIS STEP IF YOU ARE NOT ENABLING THE TELNET INTERFACE*
88: Login as "teacher" and copy the file "capalogin" from the directory
89: DIST51/PutInCAPA51 into the directory /home/teacher/CAPA51. Check
90: to make sure your permissions match the following:
91:
92: -rwsr-xr-x 1 teacher cai 585097 Jul 17 15:03 capalogin
93:
94: Make certain that capalogin is set UID mode (there is an "s" instead
95: of an "x" in the user's permissions). If not enter the following:
96:
97: > chmod u+s capalogin
98:
99: 6.) *SKIP THIS STEP IF YOU ARE NOT ENABLING THE TELNET INTERFACE*
100: For each class that telnet is enabled for, it is added as a user
101: to the system without a password. The security of the system is
102: maintained by using capalogin as the login shell. To set up the
103: demonstration class, become root then use the adduser utility to create the
104: user "nsc131s0". Enter the group id the same as the instructor (cai), the
105: parent directory to be /home/teacher/CAPA51, and the login shell
106: to be /home/teacher/CAPA51/capalogin. When you are prompted to
107: enter an initial password, hit return. You then need to edit the
108: /etc/passwd file to remove the "Nologin" field.
109:
110: For Linux systems, you will need to create the user, edit /etc/passwd
111: to remove the password field, change the group id number, change the home
112: directory and change the login shell. You will not be prompted for these
113: within the utility. Make certain the group id number is the same as the
114: instructor account. Editing the passwd file is done by becoming root
115: using the vipw command. Finally, you must delete the directory created by
116: the adduser utility, for example:
117:
118: >rm -rf /home/nsc131s0
119:
120: Depending on your system, you may not be allowed to add a user without a
121: password using the adduser utility. If this is the case, you will need
122: to manually add the user with the vipw command.
123:
124: Repeat the steps above for qns131s0 and xpc131s0 (do not add xns131s0 as
125: a user).
126:
127: The correct class entries in /etc/passwd are given below: (The paths to the
128: home directory and login shell may differ for your system.)
129:
130: nsc131s0::1004:103:Demonstration Class - Homework:/home/teacher/CAPA51/nsc131s0:/home/teacher/CAPA51/capalogin
131: qns131s0::1005:103:Demonstration Class - Quizzes:/home/teacher/CAPA51/qsc131s0:/home/teacher/CAPA51/capalogin
132: xpc131s0::1006:103:Demonstration Class - Exam Partial Credit:/home/teacher/CAPA51/xpc131s0:/home/teacher/CAPA51/capalogin
133:
134: 7.) Login as teacher and create the class called nsc131s0 in teacher's
135: CAPA51 directory by copying this directory from DIST51/PutInCAPA51
136:
137: > cd CAPA51
138: > cp -R /home/teacher/DIST51/PutInCAPA51/nsc131s0 nsc131s0
139:
140: Then, check to be certain the owner of the nsc131s0 directory is "teacher"
141: with group membership "cai".
142:
143: Repeat this step using the qns131s0, xns131s0, and xpc131s0 directories.
144:
145: 8.) Make certain a directory named "records" exists in each of the class
146: directories (e.g. /home/teacher/CAPA51/nsc131s0/records). Also, make certain the
147: ownership of all sub-directories and files is "teacher" with group membership
148: "cai". It is a good idea to check your permission with the ones below.
149:
150: > cd nsc131s0
151: > ls -lag

225:
226: 9.) The CAPA system needs to access the files just installed in the teacher
227: home directory. Make sure this directory has both group and world r-x
228: privledges.
229:
230: drwxr-xr-x 6 teacher cai 1024 Jul 17 13:43 teacher
231:
232:
233:
234: You will have similar files in the qns131s0, xns131s0, and xpc131s0 directories
235: with the same permissions. Check those also.
236:
237: The utilities for running CAPA with telnet sessions are now completely
238: installed.
239:
240: --------------------------------------------------------------------------------
241: SETTING UP THE WEB VERSION OF THE CAPA INTERFACE
242:
243:
244: 1.) It is recommended that you make a backup of the teacher/PublicWeb
245: directory and all of it's subdirectories and files before making the
246: changes below.
247:
248: 2.) Login in as teacher. Remember, it is assumed that the teacher
249: directory is in /home which may not be the case for your machine.
250:
251: 3.) Update your /home/teacher/PublicWeb/CAPA directory with the files from
252: DIST51/CopyToPublicWeb/CAPA directory.
253:
254: Go to /home/teacher/PublicWeb/CAPA and copy ExmPanel.class, ExpPanel.class,
255: GLabel.class, TScore.class, help.html from the distribution. Make sure the old
256: files for Glabel.class and help.html are replaced (they will have today's date
257: when you check permissions). Make sure all files in this directory are owned by
258: teacher and have group membership cai.
259:
260: > cd /home/teacher/PublicWeb/CAPA
261: > cp /home/teacher/DIST51/CopyToPublicWeb/CAPA/ExmPanel.class .
262: > cp /home/teacher/DIST51/CopyToPublicWeb/CAPA/ExpPanel.class .
263: > cp /home/teacher/DIST51/CopyToPublicWeb/CAPA/GLabel.class .
264: > cp /home/teacher/DIST51/CopyToPublicWeb/CAPA/TScore.class .
265: > cp /home/teacher/DIST51/CopyToPublicWeb/CAPA/help.html .
266:
267: 4.) Update your /home/teacher/PublicWeb/CAPA/capa-bin directory with the files
268: from DIST51/CopyToPublicWeb/CAPA/capa-bin directory. Particularly, you will need
269: to update web.settings, capadiscuss_html, capahtml, and webpage.
270:
271: > cd capa-bin
272: > cp /home/teacher/DIST51/CopyToPublicWeb/CAPA/capa-bin/web.settings .
273: > cp /home/teacher/DIST51/CopyToPublicWeb/CAPA/capa-bin/capadiscuss_html .
274: > cp /home/teacher/DIST51/CopyToPublicWeb/CAPA/capa-bin/capahtml .
275: > cp /home/teacher/DIST51/CopyToPublicWeb/CAPA/capa-bin/webpage .
276:
277: 5.) Check permissions in the capa-bin directory. Your permissions for the files
278: in PublicWeb/CAPA/capa-bin should like the following:
279:
280: > cd capa-bin
281: > ls -l
282: -rw-r--r-- 1 teacher cai 33363 Jul 17 15:51 capadiscuss_html
283: -rws--x--x 1 teacher cai 519680 Jul 17 15:51 capahtml
284: -rw-r--r-- 1 teacher cai 223 Jul 17 15:51 class.conf
285: lrwxrwxrwx 1 teacher cai 7 Jul 17 15:51 class.html -> webpage
286: lrwxrwxrwx 1 teacher cai 7 Jul 17 15:51 email.html -> webpage
287: lrwxrwxrwx 1 teacher cai 7 Jul 17 15:51 getid.html -> webpage
288: drwxr-xr-x 2 teacher cai 1024 Jul 17 15:51 teacher
289: -rw-r--r-- 1 teacher cai 4460 Jul 17 15:51 web.settings
290: -rwx--x--x 1 teacher cai 1141535 Jul 17 15:51 webpage
291:
292: If your permissions do not match the ones above, change them so they do.
293: Read step #6 before changing your permissions for capahtml. You may
294: also see files called web_access.log and ids.log in the capa-bin
295: directory. These files are automatically generated by the CAPA software.
296:
297: The system links to the webpage program should still be there from the
298: previous CAPA installation. If they do not exist, enter the following:
299:
300: > ln -s webpage class.html
301: > ln -s webpage emailid.html
302: > ln -s webpage getid.html
303:
304:
305: 6.) If the user "teacher" does not own the webserver (for example, the
306: webserver is owned by the user "www"), then you will need to make the
307: capahtml file set UID.
308:
309: > chmod u+s capahtml
310:
311: If "teacher" owns the webserver, then leave capahtml in the default executable
312: permissions as listed in step 4.
313:
314: 7.) Edit /home/teacher/PublicWeb/CAPA/capa-bin/web.settings
315: Change the first line:
316: set machine capa2.nscl.msu.edu
317: To read:
318: set machine your.machine.name
319:
320: 8.) Edit /home/teacher/PublicWeb/CAPA/capa-bin/class.conf by adding
321: the following lines (note that you may have different paths than
322: /home/teacher):
323:
324: nsc131s0 /home/teacher/CAPA51 teacher {class emailid}
325: qns131s0 /home/teacher/CAPA51 teacher {class}
326: xpc131s0 /home/teacher/CAPA51 teacher {class}
327:
328: 9.) Update your /home/teacher/PublicWeb/CAPA/capa-bin/teacher directory with the
329: files from DIST51/CopyToPublicWeb/CAPA/capa-bin/teacher directory. Copy the files
330: capasbin and capadiscuss to this directory from distribution.
331:
332: > cd teacher
333: > cp /home/teacher/DIST51/CopyToPublicWeb/CAPA/capa-bin/teacher/capasbin .
334: > cp /home/teacher/DIST51/CopyToPublicWeb/CAPA/capa-bin/teacher/capadiscuss .
335:
336: Check that both these files are owned by teacher and have group membership cai.
337: These files should also have executable permission and capasbin should be set
338: UID (there is an "s" instead of an "x" in the owner's permissions). If not,
339: enter the following:
340:
341: > chmod u+s capasbin
342:
343: 10.) Make the changes that you made above for the teacher directory to all
344: other instructor directories. Make sure they are owned by the appropriate
345: instructor and have the appropriate group membership.
346:
347: 11.) Go to /home/teacher/Public/demolibrary and make sure Graphics and Links
348: point to /demolibrary/Graphics and /demolibrary/Links. If they point to the old
349: demolibrary, make changes by removing the links and adding the new ones.
350:
351: > ln -s /demolibrary/Graphics Graphics
352: > ln -s /demolibrary/Links Links
353:
354: 12.) Restart your webserver.
355:
356:
357: --------------------------------------------------------------------------------
358:
359: FINAL INSTRUCTIONS
360:
361: 1.) Modify /demolibrary/Tools/StdMacros
362:
363: Replace the line
364: /LET machine_name="capa2.nscl.msu.edu" // needed for labeling tools
365: With
366: /LET machine_name="your.machine.name" // needed for labeling tools
367:
368: 2.) Double check to be certain the ownership and group membership
369: for each of the files and subdirectories under the teacher account
370: consistently have "teacher" as owner and "cai" as group. Also double
371: check that the demolibrary directory in /home/teacher/DIST51 is owned
372: by "teacher" and has group membership "cai". (Note that your instructor
373: directories under PublicWeb/CAPA/capa-bin will be owned my the appropriate
374: instructory).
375:
376: 3.) Make sure that the user teacher, the owner of the webserver, and
377: root have the commands allcapaid, perl and gs (ghostscript command) in
378: their path. You can check this by using the which command. If it is
379: in the user's path, you will then be shown where the directory for the
380: command is located.
381: For example:
382:
383: > which perl
384: /usr/bin/perl
385:
386: 4.) If teacher is somewhere other than /home, then you need to edit the
387: capa.config files in the nsc131s0, qns131s0, xns131s0, and xpc131s0 directories.
388: Change the following lines to refer to the correct path:
389:
390: quiz_path = /home/teacher/CAPA51/qns131s0
391: exam_path = /home/teacher/CAPA51/xns131s0
392: supp_path = /home/teacher/CAPA51/xpc131s0
393: .
394: .
395: .
396: correction_path = /home/teacher/CAPA51/xpc131s0
397:
398: 5.) In each of the capa.config files (DIST51/PutInCAPA51/nsc131s0/capa.config,
399: ..., ...skeleton/capa.config, etc. and /home/teacher/CAPA51/nsc131s0, etc.) edit
400: the print commands to match the ones that you use from your server where CAPA is
401: installed. The comments in the printing configuration section of the capa.config
402: file will direct you how to make these changes.
403:
404: Also, edit the line:
405:
406: capa_server = your.machine.name
407:
408: In the "Extrapolate Scores Applet" section to read the name of your capa server
409: in each of the capa.config files.
410:
411: 6.) Print the Manual.
412:
413: 7.) Take a look at the sets in nsc131s0. In particular sets 3-17 (a
414: detailed list of the templates).
415:
416: 8.) Read the READMEsecurity.txt file.

437: ADDING ADDITIONAL USERS
438:
439: 1.) Add the new user to your system with group membership cai. If you are
440: unsure about doing this, follow the same instructions outlined in the
441: "INITIAL SETUP" section of the README.txt file except use the new user's name
442: instead of "teacher" (and the new group's name if the new instructor to be added
443: to the CAPA system should be in a different group other than "cai").
444:
445: 2.) Login as root and add a directory to the capa-bin directory with the same
446: name as the new instructor's user name. For example:
447: > mkdir /home/teacher/PublicWeb/CAPA/capa-bin/instructor-name
448:
449: 3.) Copy the files capasbin and capadiscuss from
450: teacher/DIST51/CopyToPublicWeb/CAPA/capa-bin/teacher into the new
451: instructor-name directory. For example:
452:
453: > cd /home/teacher/PublicWeb/CAPA/capa-bin/instructor-name
454: > cp /home/DIST51/CopyToPublicWeb/CAPA/capa-bin/teacher/capasbin capasbin
455: > cp /home/DIST51/CopyToPublicWeb/CAPA/capa-bin/teacher/capadiscuss capadiscuss
456:
457: Make sure that the permissions for the the capasbin and capadiscuss files
458: are executable and that capasbin is set UID mode (there is an "s" instead
459: of an "x" in the user's permissions). If not, enter the following:
460:
461: > chmod 755 capasbin capadiscuss
462: > chmod u+s capasbin
463: > ls -l
464: -rwxr-xr-x 1 instructor cai 23453 Mar 16 11:15 capadiscuss
465: -rwsr-xr-x 1 instructor cai 843150 Mar 16 11:15 capasbin
466:
467: 4.) Change the ownership of the instructor-name directory and all of its
468: files to the appropriate user ("instructor-name") and group (i.e. "cai").
469: > cd /home/teacher/PublicWeb/CAPA/capa-bin
470: > chown -R instructor-name:cai instructor-name
471:
472: 5.) Finally, double check that the instructor owns his/her directory
473: in the capa-bin directory and that the instructor's capasbin and capadiscuss
474: have the correct ownership and permissions.
475:
476: --------------------------------------------------------------------------------
477:
478: ADDING ADDITIONAL CLASSES
479:
480: Once an instructor account is created, you can add classes to the
481: system as needed. Below we call the owner of the class "instructor"
482: and the class "classname". Your class's name should be 8 characters
483: max if you will be using the telnet interface. We name our classes
484: names such as phy183s0 (physics 183, spring semester, 2000) and cem142f0
485: (chemistry 142, fall semester, 2000).
486:
487: If you chose not to enable the telnet interface, then skip steps
488: 1 and 2 below.
489:
490: 1.) *SKIP THIS STEP IF YOU ARE NOT ENABLING THE TELNET INTERFACE*
491: Use the adduser utility to create the user "classname". For Digital
492: Unix and Solaris operating systems:
493: a.) Login as root
494: b.) Change directory to /usr/sbin
495: c.) Type the command "adduser". You will be prompted for information.
496: -Make certain the user "classname" is a member of the same
497: group as the instructor.
498: -Use /home/instructor/CAPA51 as the parent directory and
499: /home/instructor/CAPA51/capalogin as the login shell.
500: -Do not add a password.
501: d.) Remove the system created classname directory. (Your absolute
502: path may differ from /home.)
503: >rm -rf /home/instructor/CAPA51/classname
504:
505: For Linux operating systems:
506: a.) Login as root
507: b.) change directory to /usr/sbin
508: c.) Type the command "adduser classname".
509: (or "useradd classname" depending on your system)
510: d.) If prompted for a password, do not add one.
511: e.) Delete the directory created by the adduser utility. (Your absolute
512: path may differ from /home.)
513: >rm -rf /home/classname
514: NOTE: Depending on your system, you may not be allowed to add a user
515: without a password. In that case, you will have to add the user
516: manually using the vipw command.
517:
518: 2.) *SKIP THIS STEP IF YOU ARE NOT ENABLING THE TELNET INTERFACE*
519: Edit the password file. For Digital Unix and Solaris operating systems:
520: a.) Edit the entry for "classname" in the /etc/passwd file with the vipw
521: command.
522: -remove the encrypted password field (or the field "NoLogin").
523: -Check to be certain the home directory and login shell are
524: correct.
525: b.) A sample /etc/passwd entry is given below:
526:
527: phy123s0::1007:103:Intro Physics I:/home/instructor/CAPA51/phy123s0:/home/instructor/CAPA51/capalogin
528:
529: For Linux operating systems:
530: a.) Edit the entry for "classname" in the /etc/passwd file.
531: -Remove the encrypted password field (or the field "NoLogin").
532: -Change the group id number to match the group id number in
533: the instructor's account
534: -Change the home directory to
535: /home/instructor/CAPA51
536: -Change the login shell to
537: /home/instructor/CAPA51/capalogin
538: b.) A sample /etc/passwd entry is given below:
539:
540: phy123s0::1007:103:Intro Physics I:/home/instructor/CAPA51/phy123s0:/home/instructor/CAPA51/capalogin
541:
542: 3.) Make the classname directory. Login as the "classname" owner, copy
543: the contents of /home/teacher/DIST51/PutInCAPA/skeleton into the new class
544: directory.
545: > cd /home/instructor/CAPA51
546: > cp -R /home/teacher/DIST51/PutInCAPA51/skeleton classname
547:
548: Make certain there is a classname/records directory present.
549: The following are a few files you might want to edit to tailor to your
550: particular course:
551:
552: welcome.msg and goodbye.msg (both for telnet), capa.config, HWTop, (QuizTop,
553: ExamTop), and classl
554:
555: Be certain to retain the exact character spacing in the classl file.
556:
557: 4.) Check to be certain the owner of the /home/instructor/CAPA51/classname
558: directory, sub-directories and files is "instructor" with group membership
559: "cai" (or whatever the correct group is).
560:
561: 5.) Once you have created your problem sets, your course is ready for
562: telnet access. That is, if you chose to enable the telnet interface.
563:
564: ------------------------------------------
565:
566: Setting up WWW access for this same course:
567:
568: 1.) Edit /home/teacher/PublicWeb/CAPA/capa-bin/class.conf by
569: adding the new class. Example:
570:
571: classname /home/instructor/CAPA51 instructor {class getid emailid}
572:
573: 2.) Make certain a copy of capa.config exists in the "classname"
574: directory. Also double check the ownership and group membership of
575: the classname file and all of its sub-directories and files have the
576: appropriate owner and group membership.
577:
578: 3.) The instructions above were for using CAPA for homework. If you
579: want to use CAPA for quizzes, exams, etc. then read the next section.
580:
581: 4.) Edit the paths and printing configuration section in the capa.config
582: file. Edit the dept_name, etc in the HWTop (QuizTop and ExamTop). Also
583: edit the classl file, making sure the instructor and TAs all belong to
584: the admin_section(s) (see capa.config file and edit admin_section if
585: appropriate).
586:
587: Your "classname" class is now ready to use for homework.
588:
589: --------------------------------------------------------------------------------
590:
591: ADDING ACCESS FOR QUIZZES, EXAMS, EXAM PARTIAL CREDIT, ETC.
592:
593: 1.) Quiz, exam, and other access are added as separate "classes".
594: You may choose to name them similar to the convention of the
595: demonstration "classes" nsc131s0 (homework), qns131s0 (quizzes),
596: xns131s0 (exams), and xpc131s0 (exam partial credit).
597:
598: 2.) To use CAPA for more than just homework, install your quiz,
599: exam, etc. directories using the instructions above but use the
600: appropriate skeleton directory (skeletonQuiz, skeletonExam). For
601: supplementary course work, such as exam partial credit, then just
602: use the skeleton directory. Follow the guidelines below when
603: setting up web access in the class.conf file.
604:
605: 2.) Below are some guidelines assuming you are using the entirety
606: of CAPA by adding quiz, exam, partial credit (supplemental), and other
607: access for a physics class PHY 123:
608:
609: qph123s0: Enable telnet if you do so and allow class.html
610: access only. This gives you the option of giving
611: take-home quizzes, but the students cannot use
612: emailid.html or getid.html, they must get their
613: CAPA ID in class. In the capa.config file, you
614: would enter the following:
615:
616: qph123s0 /home/instructor/CAPA51 instructor {class}
617:
618: xph123s0: Do not enable access through telnet or web interface.
619: If you do want telnet or web access, please be careful
620: to protect you exams by setting the correct open and
621: due dates and it is highly recommended that you do
622: NOT allow the students to retrieve their ID for further
623: protection. Consult the Manual about due dates.
624:
625: xpc123s0: You have the option in CAPA to allow students to take
626: the exam again at home and apply those points to their
627: exam score as partial credit. Set up similiar to quizzes
628: and BE CAREFUL about open dates and due dates to protect
629: your exam.
630:
631: oph123s0: Use this for whatever you wish, such as supplemental homework.
632:
633: 3.) Edit the paths in the capa.config file in each of the classname
634: directories. Edit the dept_name, etc. in the HWTop (QuizTop and ExamTop).
635: Also edit the classl file, making sure the instructor and TAs all belong to the
636: admin_section(s) (see capa.config file and edit admin_section if appropriate).
