The instructors tell you over and over to pay attention to the learning objectives, self checks, and end of chapter questions for a reason!!!
This is not to say that every question on the proctors are verbatim copies of these, but it serves as a very good outline for what to study.
As long as you have a good grasp of what these questions are asking for, you should be fine.
Read the questions CAREFULLY.
Write ALL you know in your answer, don't take it for granted that the person grading you knows what you are talking about. Detail Detail Detail!!
Answer the ones you KNOW first, then go back and re-read the ones you passes over. Sometimes just getting in the "mind-set" unlocks and loosens up the brain, so to speak - and what you think you didn't know or remember will come flooding back when you "are in the groove".
Don't sweat it. It's only a test - just a test. It can't eat you.
