I don't know about any online courses, but PR
had classes at my high school. This was when I first started studying for the SATs...
First of all, all the students there (except 1) were aiming for like 1600-1800 (as their top score). Now I'm not saying that these are bad scores to aim for at all, but because I was aiming for a 2400, these kids held me back A LOT. Second of all, the teacher was retarded. She was completely, COMPLETELY incompetent. If she took the SAT, I doubt she would have gotten a 1400 (yes I'm talking about the new one -_-). The PR
tutors try to force you into using a certain method (even if your method for math takes half the time, they'll try to make you use THEIR method). In fact, self studying was about 5 - 7 times more efficient I think (no exaggeration). The only reason I stayed in the course was to take their diagnostic tests, which were actually the only helpful things the course provided.
So all in all, I don't recommend a PR
tutor (don't know about online course, but I wouldn't risk that either?)
Alright, sorry - just venting my frustration.
