Best GMAT Prep Courses for October 2025

Target Test Prep offers a variety of plan options ranging from self-study to live online classroom experiences. Access to self-study material can be paid for on a month-by-month basis if you just need a little help, or you can save by buying access for four or six months.

All of Target Test Prep’s plans include comprehensive resources to help you pass each section of the GMAT (Quant, Verbal, Data Insights). You’ll get:

• A personalized AI-driven plan and daily study calendar
• Over 4,000 Quant, Verbal, and Data Insights practice questions
• 1,200 Quant and Verbal digital flashcards and custom flashcards
• Custom practice tests
• Error tracking to find weak areas
• 24/7 live online support

Upgrade to the TTP OnDemand plan to get access to live weekly office hours where you can ask experts questions. Or get Live Instruction + TTP OnDemand to get an additional 40 hours of live classes, personalized homework, and access to a Slack channel where you can talk about the GMAT (this plan takes a limited number of students).

On top of all that, Target Test Prep offers one-on-one tutoring with well-qualified instructors who have scored in the 99th percentile on the GMAT. This is expensive but not uncommonly so; tutoring is available from five hours per month ($1,700) to 40 hours per month ($12,040).

GMAT prep courses can get pretty expensive, but you don’t need to sign up for a payment plan to get access to high-quality instructors. PrepScholar offers a pair of affordable GMAT self-study courses, a basic plan at $139 (three months) and a more comprehensive plan at $259 (four months). Tutoring is available as well, for a higher price.

PrepScholar begins with a diagnostic test to see where you currently stand. Then, the program builds a personalized curriculum based on your strengths and weaknesses. PrepScholar breaks the GMAT down into 31 pieces and tests your knowledge of each with a short quiz.

PrepScholar has a 60-point score improvement guarantee, which is lower than some other courses but provides a complete refund if you meet the terms. You must finish the course, take an official GMAT within 60 days, and score below 760 and fewer than 60 points higher than your previous score.

Manhattan Prep has been helping people pass professional exams for over 20 years, and the experience shows in its comprehensive course offerings. Whether you can get by studying on your own or you’re able to spend more on live courses or tutoring, Manhattan Prep (powered by Kaplan) has you covered. And the company’s highly rated mobile apps mean you never have to miss a study session.

The self-study toolkit, available for $359, comes with physical and digital resources. You’ll get books on the Quant, Verbal, and Data Insights sections, a Foundations of Math program, six full-length tests, weekly reading and problem sets, and more. 

The next step up is the On Demand course, which adds 25+ video lessons, 10 hours of math workshops, and a Dynamic Question Set Builder to create your own quizzes. This course can be upgraded to On Demand + Admissions, which includes extra content and workbooks designed to help you get into top business schools.

You can also choose from:

• Live Course: Live classes taught by 99th-percentile instructors
• GMAT Advanced Course: For those who already scored at least a 595 on the new GMAT
• GMAT Bootcamp Course: A speed run through the content over three weeks rather than two months
• Tutoring: One-on-one sessions with 99th-percentile instructors
• Executive Assessment: Prepare for the Executive Assessment exam, which you can take in addition to the GMAT

Manhattan Prep’s classes are more expensive than average, based on our research into GMAT prep schools, but you can pay in installments if you wish.

Magoosh has a much simpler course menu than many of the other schools included in our research. You can choose from two basic courses: a six-month option ($249) and a 12-month option ($349), which you can choose to pay for in installments. They each come with the same course materials; the only difference is the amount of time you can access them.

Students get access to:

• Instruction on the Quant, Verbal, and Data Insights sections
• 200+ video lessons
• 800+ practice questions
• 2+ diagnostic tests
• Ability to ask an expert questions
• Exam score predictor
• Ability to switch to GRE for free

These simpler courses omit some of the more elaborate features of other schools, like live classes or tutoring. Magoosh also has a Premium + Admissions course, with 12 months of GMAT prep plus a wealth of resources to help smooth out your business school applications.

Magoosh offers a score increase guarantee of up to 70 points on a sliding scale, depending on your previous score. You get a 70-point guarantee if you originally scored up to 575, a 60-point guarantee if you scored 585, a 50-point guarantee if you scored 595, etc. This guarantee takes effect if you meet certain requirements, like finishing the course and taking the GMAT exam. 

Along with the score improvement guarantee, Magoosh stands out by also offering a seven-day no strings attached money-back guarantee—if you no longer want a course within seven days of purchasing, you can get a full refund.

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.
