I took a 9 session, live online course with Elaine Loh at Manhattan Prep. I couldn't speak more highly of her and the overall experience. I got a 580 on my first practice test at the start of class. My score slowly went up throughout class and peaked on test day at a 730 about 5 months after the start of class. Elaine brought a ton of enthusiasm and motivation to every single class. She also was extremely responsive and helpful after the class ended. She gave me multiple suggestions and strategy tips in the weeks leading up to my exam. I was able to increase my verbal score 3 points thanks to her last minute advice. I recommend Manhattan and Elaine especially to all GMAT takers.
