\label{Testbank_Formatting} Four requirements must be met to ensure that you will succeed in building LON-CAPA problem files using your plain text file containing testbank questions. \begin{enumerate} \item 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. \item All questions must occur before any of the answers. Each question 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 . \item One or more correct answers should be provided for all questions (although blank answers may be provided for \textit{essay} questions). Answers should be numbered sequentially, using the same scheme as used for the questions, and must occur after all the questions. \item \textit{Multiple choice} and \textit{multiple answer correct} questions should consist of (i) the question number followed by (ii) a question stem 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) \item If \textit{fill-in-the-blank} or \textit{multiple answer} questions have more than one correct answer, each answer should appear in a comma-, tab-, space-, or new line-delimited list. \end{enumerate}
