I took Max's math course based on strong recommendation from my colleague who went to Wharton MBA. Quantitative section of GMAT was one of my shortcomings but Max's teaching method and approach in problem solving was very unique and easy to follow. The course provided questions that were very similar to actual GMAT and thoroughly covered how to tackle problems and manage my time.
On the test date, I stayed calm and used what I had learned to solve problems and received a score I hoped for long on the screen. Strongly recommend the program to anyone finding Quantitative section challenging.
