I was wondering how some of the other instructors involved in this forum handle their test reviews. I tend to have a review guide that the students work on in-class the day before the exam. I encourage them to work together, but allow them to work individually if they so choose. Following the group work, if there are any questions they couldn't find the answer to, we address those in-class. While this is effective, it tends to get a little noisy which impedes the progress of some students, so I'm curious as to some other effective methods of review.
