I really appreciate Dan Bernstein's help! He made my GMAT score improve significantly (by 200 points) in only two months. I don't think I was able to get into my dream school without his mentoring. He was really good at listening to my concerns and pointing out the issues and directions for me very effectively. More importantly, he was also great at encouraging me during the most difficult time. He was not only dedicated in the class but also very responsive after class when I wrote his emails. I was very lucky to have Dan as my GMAT tutor! I would highly recommend you to try him as your GMAT tutor.
