best place for prep

<p>So I was thinking of doing sat prep with a company to prepare for a spring sat. I'm thinking of doing the elite winter boot camp. Does anyone have experience with elite and any idea how much the WINTER boot camp would cost (I've heard the summer one is around $2500) And anyone have experience with other companies like excel, c2, Ames, Princeton review, Kaplan for classes? I really want to improve my essay score and my critical reading and if anyone knows which test prep company/materials are best for those areas it'd help a lot!! ☺</p>

<p>Anyone???</p>
