Hey CC, I really need help on improving my SAT score so I can go to my #1 college choice. I’ve looked into buying a SAT prep, online, self-paced course and I really need help from someone who has tried either the Prep Scholar program or the Green Test Prep one, my SAT is coming up and I need as much help as possible.Thanks.
There have been many threads on both of these businesses–search is your friend, @isaacro15 !
Recommend PrepExpert. Did their online course and ended up scoring 1590 
My son took the SAT in October and got 1260. He buckled down and did the PrepScholar program. He put in about 40 hours. He just got his score back and improved by 130. They do guarantee a 160 points improvement if you master all the lessons.
@Helismother - did you get the refund?
