<p>that is because math II has a huge curve (790 means like 7 questions wrong) whereas math I basically has no curve (660 means like 7 questions wrong). and that 630 wasn’t really affected by your 8 on the essay, i got a 6 on my essay and a 710. if you use the SAT official study guide well, i think you can surely get 800/750/700</p>
<p>I think the advice is usually the same for everyone. For math, take practice tests and try targetting the types of questions that seem to confuse you. Aside from the blue book, I think it’s really helpful to have to supplementary books for the specific sections. Math ones often teach you efficient ways to tackling some questions. For CR, I honestly think just doing a lot of passages is useful. I improved from 700 to 780 by just practicing (over several months). For writing, the specific study books for that usually show you the most common grammar mistakes on the SAT. I found that useful. Basically, take advantage of your time and practice ;)</p>
