"I highly recommend Mark's GRE preparation course. I've taken several of his classes, including the Basic Math Refresher, and I find them extremely helpful. He really targets the math classes to help build the skills needed for the quantitative section of the course. I had enrolled in the Kaplan course prior to taking Mark's class, but I found that Mark's course better suited my needs. I was disappointed with the level of instruction Kaplan provided. Mark's years of experience outshine the competition. The classes are fun and he packs a lot of information into each session." --Barbara Warden
