Veritas Prep
One of the most important factors in looking for a GMAT prep course, or any prep course for that matter, is looking at the credentials of your instructor. Do they know the GMAT inside and out? Have they taken it? How well did they score on it, and what are their strengths? With Veritas Prep, you need not worry about the legitimacy of your teachers because the company does not use tutors who did not rank in the 99th percentile on the exam. They have multiple methods of instruction available, ranging from in-person to completely online.
Kaplan Prep
Not only does Kaplan offer various methods of classroom experiences, but for a premium, they will send a tutor to your home for one-on-one sessions. They also offer an exclusive Test Day Experience; whether you receive your test prep in-person in a classroom or online at your own pace while at home, you will get to attend an actual Pearson testing center for a practice exam, simulating the real thing.
