There are some markings in the text (but not on the correct answers in the problem sections). In the text sections, I've marked the areas where I made mistakes in the problems and in other problem sets, so to put it another way, if you memorize the marked areas, you'll reach the passing score (several questions on the actual exam came from the marked areas). I studied for about 2 hours a day using this textbook and problem sets, starting about two weeks before the exam. I think you get used to it by working through the problems, and the problems are designed with practice in mind (if you'd like me to list other problem sets, please let me know). The bonus is something I received at a training session. Please use it as a supplementary material.
