- Course credits for a particular institutional code can be provided as a
third item returned by localenroll::validate_instcode()
- Course credits can be specified for an official course (or retrieved from
localenroll::validate_instcode) or an unofficial course as part of a course
request
- Credits earned for a course can also be different for a specific student
(e.g., retrieved from institutional classlist data), or specified when
CC adds a student to a course via the web GUI.
