My instructor, Isabella Raicu (along with Kevin Parrish as TA), taught the course material very well. My experience, however, was slightly subpar compared to the other Prep Expert course I took. The lesson felt boring at times with no jokes to lighten the mood. Also, I must mention that the breaks added up to 45 minutes some lessons, which felt a bit long . Overall, I feel the strategies are worth it and the practice is useful if you're looking to improve your SAT score. The cost is high, but if you do all the homework and tests, you will likely find the course valuable.
