When I read about this course, I was skeptical about their claims of score improvement guarantee. While I was always quite comfortable in the quant section, scoring Q48-49 in the practice tests, I couldn't reach to a score of Q50-51. I felt like I was hitting a wall. Thats when I decided to join Math Revolution. The course teaches you unique concepts about both DS and PS sections. Especially in DS section, I could see a great improvement in time and accuracy when I applied their method. The course also helps you to tackle all types of trap questions that are tested in GMAT, making it a very relevant practice source.
Overall, this course helped me get a score of Q50, score that I would have struggled to hit otherwise. Take advantage of their free trial to learn about their teaching methods. I would highly recommend this course to anyone who is looking to hit a high quant score!
