The correct answers for multiplechoice and truefalse are recorded in the file mn-correct. Each line holds the correct answers for a different exam. The first three digits hold the exam number. For multiplechoice questions the letter label corresponding to the correct option is recorded. For truefalse questions, A is recorded if the statement is ture and B if it is false. Finally for shortanswer questions, A is recorded but it has no meaning.
For instance if two exams are created, with one exercise and six questions of the multiplechoice type, the mn-correct file may look like:
001AABDEF
002BCAADE
