My instructor was Shaan Patel. He was amazing, very engaging and he was good at communicating with the students beyond just spitting out SAT knowledge. He would be personable and talk about his own personal experiences to help us. My score went from a 1400 to a 1470 with the course (and I do believe I could've gotten more if I had done more of the practice material, but due to personal matters I wasn't able to do all of it. For most students my situation should not be an issue). I really appreciated the vast amounts of practice material available to us as well as the tips on where to find yet more practice. Unlike many other courses, PrepExpert readily admitted any limitations in its own course instead of trying to claim that it could do literally everything. It was really refreshing. The practice tests were also almost identical to the official Bluebook one, which was really good for preparations. Overall, a very comprehensive and awesome course that was much more personable and had much more prep material than previous preparation courses I've taken.
