Which one of these three SAT prep centers is the best?

The three SAT prep centers that I am considering are Princeton Review, Kaplan Test Prep, and Elite Test Prep.

I’ve taken classes with Elite before but i was just looking for some more opinions out there. Please help me decide.

I will be a senior next year and I am not happy with my SAT score. This is really the crucial time period that I need to focus and concentrate in to get into a great college.

Thanks in advance! Please give me comprehensive answers with Stats, personal experience etc. The more information the better! :)

Kaplan SAT prep CD-ROM?

I take the SAT in November, and I am considering buying the Kaplan Test Prep SAT ACT PSAT 2007 Platinum Addition on CD-ROM, because not only would it help with the SAT, but perhaps with the ACT that I retake in the spring. However, how much different are the 2007 prep guides compared to this years? Is it so significant that it wouldn’t help? Any opinions and/or suggestions would be helpful!

Is Kaplan’s SAT prep course worth the money?

I was surprised to see that Kaplan’s SAT test prep costs over 0 for 12 prep classes. I’m also aware of the study guides at bookstores and College Board prep sites, but want the best preparation for the test.

Is the Kaplan test prep worth the money? Have you taken it and did it benefit you? If so, how?
