What should I do to prepare?

<p>My math scores are legit.. with a little review i could get a 750-800 easily.
But I'm really not too great at CR and Writing, i usually only get around the 600 range on practice tests and such. I'm taking a course at Princeton Review just because that is the popular norm i dont know how much that will help.. just looking for advice, i am aiming for a 2200+</p>
