<p>Not to be mean, but I think that a 700 on each section is a little high for you to be aiming at. I would recommend Princeton review so you can get the basics down first though.</p>
<p>Not to be harsh, but with a 21 on writing, you need a teacher. It means you have no clue with anything that has to do with writing. Until you get you basics up to par then move on to prep books</p>
<p>Either way, calc is quite useless on the SAT. Focus mainly on algebra and geometry. I recommend Princeton Review for tips and blue book for practice</p>
