Best PSAT and SAT test prep?

Hi and welcome to my blog,
I opened this blog to help anyone who is preparing for his SAT.
I remember myself when I started - I was so lost and in such a panic.
Luckily I got this great SAT guide that helped me a lot . So study hard and good luck!
My high school invited me and about 20 other students to retake the PSAT as a junior in hopes of qualifying for the National Merit Scholarship. The school offered counseling and encouragement, but no help with test review.
Which prep course is preferred? Princeton Review or Kaplan or other? Would I benefit from a class review (about 0) or online review or would a good PSAT review book be sufficient? Also, I’ll have the most time to prep during the summer versus early next fall due to heavy AP course load next year, but I wonder if I’ll score higher if I study closer to the time of the exam. Are the classes worth 0?
I’ll also be taking the SAT the same year. Any hints about how best to prepare for both? Thanks.
Sophomore PSAT score 187; class rank top 7% soph year (with AP courses).
Princeton Review is the best. I just studied the books and those were unbelievably awesome. they teach you everything in such a way that you don’t even need a teacher and you feel like you are reading a Harry Potter.
BUT, I totally believe that the in-class program will be much much better and could possibly help you for at least a 2300/2400 on the SAT (believe me, it’s easy). all you need to do is pay attention and work hard. only then will you get to party harder later
I thought the Princeton Review had the best class.
