Daniel Lee is probably one of the best and most interesting instructor. Prep Expert is very useful towards those who need that extra boost in their SAT score. It may not be a guaranteed 200 points because it will vary depending on how much you put work into the class. It might even be 400 points if you work hard enough and think hard enough. The class is easy and the class is fun! Very helpful indeed. Daniel Lee was a great instructor and friend to us all students. His fun attitude makes the class a whole lot more interesting and diverse. Thank You Daniel Lee! it has been a blast learning the confines of the SAT with you!
