TestMasters LSAT Course Reviews

Max Han | UC Irvine Before TestMasters 145 After TestMasters 165

“For anyone considering a LSAT preparation course, I highly recommend TestMasters. TestMasters is simply the best. I was introduced to their program by the legendary master himself, Robin Singh. I was a freshman in college when one day I noticed a flyer for a TestMasters LSAT information session. I had nothing to do so I decided to check it out. He explained the course and his methods, but what really convinced me was his impressive record of LSAT scores. The man dominates the LSAT, and he is teaching you how to do the same.

When it came time to prepare for the LSAT, I chose TestMasters and I know it has been one of the best decisions I have made. However, TestMasters does not magically transform your course fee into a great LSAT score. You need to put in the effort and time. TestMasters gives you everything you need to get a great score, but you have to put the work in. You have to attend all the classes, finish all the homework, do the supplemental material, and take the supplemental diagnostics. The end result will be worth it. I went from a 140-something on my first diagnostic to a 165 on the real LSAT. And I have no doubt in my mind that can happen to you too.

My experience with the TestMasters LSAT course wasn’t limited to just getting a great LSAT score. The instructors are awesome and the facilities they choose are wonderful. I learned a lot more about logic, I noticed I read everything more carefully, and I started recognizing the numerous argument flaws people use in everyday conversations. It is simply amazing when you start noticing the logic flaws and bad arguments that people commonly make. I was really happy with my LSAT score, but I got a kick out of applying the things I learned from TestMasters to my life.

My advice to anyone seriously considering law school is to start preparing for the LSAT early and to choose TestMasters as your preparation course. TestMasters truly is “the finest and most comprehensive LSAT preparation course in the world.””

Andrew Fan | UC Irvine Before TestMasters 158 After TestMasters 171

“I believe that the TestMasters program allowed me to reach my full potential on the LSAT. It enabled me to see the inherent logic underlying each separate type of question that appeared on the test and utilize specific techniques to easily see the correct answer. Additionally, the manner in which the course materials and diagnostic tests categorize the different logical reasoning questions allows you to see the types of questions that you struggle with, which gives you the chance to focus on your weaknesses. In the end, I think the TestMasters course strategies guide you towards reaching an elite score, while some of the other companies only try to get you a decent score.”

Megan Lencek | Cal State Fullerton Before TestMasters 143 After TestMasters 154

“The LSAT isn’t a test that the majority would score particularly well on right off the bat. It requires so much time and dedication in practicing the material. TestMasters, in comparison to other courses, offers by far the most instructional time, which was so important in getting students like myself to spend the necessary hours engaging in the material in order to do well on this test. My instructor Dorothy Moneymaker was PHENOMENAL. It is because of the TestMasters strategies that I had a dramatic 11-point increase in my score.”

Adam Lubliner | Whittier College Before TestMasters 151 After TestMasters 165

“TestMasters is certainly the course to choose for LSAT preparation. Having taken another LSAT prep course but not performing as well on the actual exam as I would have liked (receiving a 151), I was skeptical as to whether I was actually able to improve at all. However, with constant practice and the abundance of helpful materials TestMasters provides, I raised my score to a 165 the next time I took the actual test. I made sure that I covered the majority of the required work, and I utilized much of the supplemental material. In addition, my instructor was very engaging and helpful. I am certain that her positive reinforcement and willingness to provide assistance greatly enhanced my performance on the actual LSAT. I believe that any student willing to put in the time and effort that Testmasters deems necessary will find significant improvement far from impossible.”
