Obviously everyone has an opinion on this, and none are wrong. The one thing I learned taking these tests myself (SAT, Series 7, insurance....) is that you need to learn how actually take the test itself. The material is already known for the most part. My son would lock himself in a room with an actual practice test AND a timer, to learn how to take the the test under the pressure of working against the clock; how to skip over questions and go back, when to go for it if you have it down to 2 answers, that sort of thing. He realized when he first took the SAT that he simply didn't have time to finish. After the timed practice sessions, he scored 1500+ the last 3 times he took it (yes--he took it that many times. The last time was because he needed to take it with essay) and got an 800 in math each of those 3 times. The last time was with zero studying. He knew he knew the material, and he was confident on how to efficiently take the test.
