Hi Juan: With any style of testing, it might be a good idea to review the material and apply it to a real-life scenario (if you can). Also, one of the advantages of evaluating and then reviewing a test with the group is that it might allow a student to gain a better understanding of the rationale they need to answer similar questions that will occur on future exams. Also, it might trigger new questions about the subject matter that will help to stimulate a better understanding of the concepts overall. Regards, Barry
