Miguel Chavira is great! Would recommend him and this class to anyone looking to improve their SAT score. The times we did have to contact PrepExpert before the classes began, they were always quick to answer any questions and always polite and helpful. Miguel was willing to help and showed interest in each student. He also made the class fun which helped with it being 3 hours long. He was easy to follow and gave great tips on different strategies to help with the SAT. Saw improvement early on taking the classes. As long as you follow Miguel's instructions, complete the homework and test you WILL see improvement on your score!
