From the beginning to the end of the course, Justin Loh was one of the most engaging and funniest instructors I have ever had. Not only did Justin provide exceptional tips for improving my comprehension of mathematical and reading questions, he also made the class setting quite relaxed by telling funny anecdotes about himself. Additionally, Justin would also help the class by reviewing problems that were difficult to understand at first, and introducing new concepts I was unfamiliar with. Thanks to him, I was able to boost my SAT score by 200 points. I highly recommend Justin as an instructor for anyone looking to improve their scores.
