Ravi is the man. Breaks everything down in an easy way to understand and gives you a full fell and grasp of the difficult material. Additionally, he made it fun. Studying for the GMAT is hard and frustrating at times, but with Ravi he's able to take away that frustration and focus on one thing at a time. For me, the quant was be far the most annoying section and Veritas is able to break it down section by section in an easy to understand manner with tips and skill builders that are crucial come test day that you will need.
