I can't imagine preparing for the GMAT without Sherpa Prep. The instructors are fantastic and teach you techniques you wouldn't think of on your own. They have a lot of experience, are approachable, and tell it like it is. The course materials and layout were really helpful in keeping me on track with my study routine. I'm looking forward to working more with Sherpa (they allow you access to your student dashboard for a year after the course) for GMAT prep and MBA applications.
