<p>which book do u use for prep??
is PR sufficient for >750??
should i get barron's as well?? I don't really want to because i've already spent so much $$ on sat books,, and my my has given a copy of the practice tests on barrons..</p>

<p>US PR, if you are still confused, look up @sparknotes or check your local library to see if they have other review books</p>
