Also Great for Tutoring : Princeton Review

Investopedia's Rating
3.6 out of 5 stars

Princeton Review

Princeton Review

  • Cost: $699, $899, $1,699, $5,400, tutoring varies
  • Course length: Not disclosed
  • Guarantee: Up to 70-point improvement guarantee

Pros
  • Comprehensive or section-focused tutoring

  • Six practice exams

  • Well-established school (since 1981)

Cons
  • Courses are relatively expensive

  • Tutoring score guarantee is relatively weak

The Princeton Review has been in business since 1981, establishing a reputation as one of the mainstays of online education for students and professionals alike. 

Its most popular GMAT prep course, “GMAT 645+,” comes with 30 hours of live instruction by experts (10 hours per section), adaptive drills to prepare for the test, and office hours so you can get your questions answered. You get access for 12 months, which is as long as any other school included in our research. This course comes with a score improvement guarantee of up to 70 points. There’s a Self-Paced course as well, along with a Core Concepts course that blends guided instruction and self-study.

Princeton Review’s tutoring is available in a 10-hour package ($2,200), a 20-hour package ($4,000), and a 30-hour package ($5,400). The 10 and 20-hour packages are targeted tutoring focused on one or two of the GMAT sections, depending on what you need. The 30-hour comprehensive tutoring package covers everything, and also comes with a relatively weak score improvement guarantee. 

This guarantee doesn’t have a specific point threshold, like a 70-point improvement, but rather looks to see if you scored higher at all. That means if you score just 10 points higher, you won’t be eligible for a refund.
