Best SAT prep classes?

<p>hello, I did really bad on the psat and I'm currently a sophomore. I got a 120, I'm thinking about taking SAT prep classes this summer. Which prep class is better Kaplan vs Princeton Review vs local/private tutor courses. Local/private tutor courses are courses that can be found locally in common cities where its run by its self. Any SAT prep tips will be very much appreciated, Thank You.</p>

<p>For me, I just studied the books even to the point where I almost memorized the problems. Never had to get tutors or go to any preps since the books are very helpful and self-explanatory.</p>
