Prep Expert is a great way to prepare for the SAT! There is a lot of work to be done over the course of this class, but it definitely does help you a lot. As long as you do the work and are dedicated to studying, you will improve your score for sure with the help of this class. Daniel Lee was my instructor and he really helped make the class a good mixture of serious work, but he also made it fun and unique by making jokes, talking about other interesting things, and in general being teenage-friendly. Overall, I would recommend this course to anyone who wishes to do well on the SAT.
