I regret not having done that for the SAT, but I did end up doing it for the GRE and it boosted my score about 150 points, which was the difference between a fellowship and paying for grad school myself. Had I gone to Kaplan for the SAT, I think my life would have turned out very differently. I'm not so sure that's a good thing now, because I like my life, but things could have been even better.
But if going to a prep school is out of the question, definitely try to get the best books you can and review as many questions as you can. Even if the books are older, they can still help you prepare for the test format and for some of the subject matter that's on there. When you have enough practice that you answer the questions automatically without even thinking about them, then you're in really good shape for the test.
Repetition really helps you get ready. Other than that, do the usual. Get plenty of rest the night before the exam, but don't sleep more than normal or you may get groggy ... more.
I cant really gove you an answer,but what I can give you is a way to a solution, that is you have to find the anglde that you relate to or peaks your interest. A good paper is one that people get drawn into because it reaches them ln some way.As for me WW11 to me, I think of the holocaust and the effect it had on the survivors, their families and those who stood by and did nothing until it was too late.
