The choices can change between each time you initiate a quiz. However, if you complete part of a quiz, save, then return later, the choices will be the same, but the order will be different. Not all of the courses are set up with multiple choices though. In addition to varying sets of correct responses, some answers are mathematical. For instance it is defined such that a question might ask ("What is %d plus %d", a, b), then have choices involving the quantities: ("%d", a+1), ("%d", a*b), ("%d", a+b), etc. with a different random quantity for a and b each time you start a quiz. Interestingly, I saw one course where it had single-choice questions, with more differences than simply right or wrong. For instance one answer gave 100%, another 80%, and another 0% of the points available for that question.
