I really enjoyed this Prep Expert course, it was very informational and I have learned a lot. Ilia Kolmagorov was a great instructor, always very funny and engaging and very patient when we don't understand topics or strategies right away. The guarantee is a great incentive to enroll in a course, and I think the 6-week course was a great time frame to learn all of the strategies. I do feel that the course can be overly repetitive at points, and the homework load is poorly planned out, with some days being just one section in between classes and others being a full practice test and 3 sections. Overall, I would recommend the course to a friend because they do a great job at preparing you for the SAT.
