The <b>Testbank Upload</b> utility can be used by LON-CAPA authors to convert <i>multiple choice</i>, <i>multiple answer correct</i>, <i>fill-in-the-blank</i>, <i>ordering/ranking</i>, <i>true/false</i> and <i>essay</i> questions from a plain text testbank file to LON-CAPA problem files.  Five requirements must be met to ensure that you will succeed in converting your plain text file of testbank questions to functioning LON-CAPA problems.
        <ol>
         <li>The questions and answers you upload must be in plain text format.  Any header lines should occur before the text containing the questions and answers.</li>
         <li>All questions (including question text and all foils) must occur before any of the answers.  Each question should begin on a new line, and should start with the question number. Questions should be numbered sequentially using a number followed immediately by a space, a period, or enclosed in parentheses, i.e., 1 , 1., (1), 1), or (1 .</li>
         <li><i>Multiple choice</i> and <i>multiple answer correct</i> questions should consist of: (i) the question number followed by (ii) the question text beginning on the same line and (iii) two or more foils, with each foil beginning on a new line and prefixed by a unique letter, or Roman numeral, listed in alphabetic or numeric order, beginning at a (alphabetic) or i (Roman numeral), followed by a period, or enclosed in parentheses, i.e., a., (a), i., or (i).</li>
         <li>One or more correct answers should be provided for all questions (although blank answers may be provided for <i>essay</i> questions).  Answers should be numbered sequentially, using the same scheme as used for the questions, and must occur after <b>all</b> the questions.        
         <li>If <i>fill-in-the-blank</i> or <i>multiple answer</i> questions have more than one correct answer, each answer should appear in a comma-, tab-, space-, or new line-delimited list. For a <i>ranking/ordering</i> question, the "answer" should contain the foil identifiers correctly ordered in a similarly delimited list.</li>
