Clay overall maintains a positive tone throughout the class and is a very good instructor! He uses real life examples and provides his own strategies to get the best out of his students. The way he teaches provides an interactive setting which allows the students to express their thoughts and share their own strategies to help both the instructor and the students itself. Prep Expert has helped me so much over the six week course as the review tests, homework, and vocabulary has improved my overall score. I couldn't have increased my score without prep expert!
