TestMasters is a great place. Everyone is friendly and engaging, from the staff to the instructors. They really care about providing good customer service.
I took a summer SAT prep course and did Exam Club (which is a free service that comes with the course, that lets you do dozens of practice tests), and my SAT score went up by 300 points from a 2100 to a full score.
TestMasters is really great especially if you work hard. There's no gimmick, just good teachers and lot of practice resources available.
