This course has helped me to improve significantly! My instructor was Ilia Kolmagorov. He was very helpful and a great teacher! He gave thorough explanations and encouraged students to ask questions. From the first time I took the PSAT 8/9 to my most recent practice test, I have improved by around 300 points. All of the practice that Prep Expert provides is incredibly helpful. I also liked the pace of the class and my instructor kept the class engaged. I would highly recommend Prep Expert to anyone who is looking for structured SAT learning and preparing class.
