Being glad about choosing Justin Loh as my instructor is an understatement. Justin, in my opinion, was the perfect instructor. Not only did his teachings drastically improve my SAT score, he always made me laugh in every class without fail. He is very familiar with all the material through his experience with PrepExpert, so he never once simply read off a guide in a lecture and was always interactive. I'm genuinely grateful for Justin's efforts to keep us entertained while maintaining a fast-paced learning environment, which is the reason why I am writing such an elaborate review. Make sure to select Justin as your instructor to significantly enhance your efficiency, focus, and overall score on the SAT, and to have an experience you'll never forget.
