***For each question, do to your "comfort level." For example, question 1 has a-f (6) questions in it. If you get through (a) and perhaps (b) and you are thinking to yourself..."I've got this, I know this stuff, no worry," just move on. If, however, you do it and are not getting the correct answer, do as many as you need to become comfortable with that type of question (this could mean all of them!). Train yourself to study to learn, not to appease others.
