I took the GMAT online class with Chris Kane and had a wonderful experience. After taking a practice test, I was very nervous about the material, especially the quantitative section. Chris made mastering this material more manageable and did a great job supporting and encouraging his students. I became much more comfortable and instead of freaking out every time a question appeared, I am able to able to take a step back and review the question from the tentmaker's point of view and calmly approach the situation. He also made the 3 hour lectures fun and engaging which isn't an easy thing to do!
