I see that many people talk about time management when it comes to preparing for test. The more important that time management is attention management. You do not need to be in front of a book for an entire day if you can grasp the same information in few hours. Furthermore, we have seen that some people study less and score better whereas others spend the most of their time in front of a book and still get a lower score. This is because the test performance is based on attention management rather than time management. Therefore, try to manage your attention very wisely. Concentrating when you are studying is more important that studying for extended hours.
