They can't use your notes in the exam, so train them to use what they can. This will improve problem-solving and recall speeds. You can prepare your students by making sure they work to their own individual capacities. If you assign ten hours of practice problems per week, and a student can only put in five hours of preparation, that student will have worked to capacity. Another student might be maxed out at three hours and another might be able to put in the full ten.
Students like to see and work lots of problems.
They derive great comfort in exposure to exam-like problems. They experience great reassurance in finding out how easy the problems are and that they can solve these kinds of problems. Therefore, repetition and reinforcement should come from working additional problems, not from more lecture. Professional Publications has a variety of books and software products that you can use to assign additional problems. These products are available in the Review Course Catalog .
