The best GRE prep courses for most students are GregMAT ($5/month) for budget self-study and Manhattan Prep ($1,400+) for structured classroom instruction — your choice depends on budget, learning style, and how much score improvement you need.
Top GRE Prep Courses Ranked by Value
We evaluated GRE prep courses on five criteria: score improvement guarantees, question bank size, adaptive practice technology, instructor quality, and cost-per-point-of-improvement. No single course is best for everyone — budget, timeline, and baseline score determine the right fit.

Free vs. Paid Prep: Is a Course Worth the Investment?
For students within 5–10 points of their target score, free resources (ETS PowerPrep, Khan Academy, GregMAT free tier) are often sufficient. The marginal value of paid courses increases for students needing 15+ points of improvement, students who struggle with self-discipline, or those targeting scores above 330.
The cost-per-point calculation matters: if a $1,400 course yields a 10-point improvement that gets you into a funded PhD program worth $200,000+ in tuition and stipend, the ROI is enormous. If a $5/month subscription achieves the same improvement, the ROI is even better.
- Free resources are sufficient for most students within 5–10 points of their target
- Paid courses deliver value when you need 15+ points of improvement or external accountability
- Score guarantee policies vary — read the fine print on refund eligibility
- Live courses provide accountability; self-paced courses provide flexibility
- The best predictor of success is consistency (daily practice) not course price
How to Choose the Right GRE Course
Start with a diagnostic test to determine your baseline. If you are within 5 points of your target, use free resources. If you need 5–15 points of improvement, a mid-tier option ($5–$200) with structured content is optimal. If you need 15+ points or have a tight timeline, invest in a live course with instructor support.
Learning style matters: visual learners benefit from video platforms (GregMAT, Magoosh), while students who learn through discussion and Q&A perform better in live classes (Manhattan Prep, Kaplan).
- Step 1: Take a free diagnostic (ETS PowerPrep 1) to establish your baseline
- Step 2: Calculate the gap between your baseline and target score
- Step 3: Match gap size to course tier — bigger gaps justify bigger investments
- Step 4: Consider learning style — video self-study vs. live instruction
- Step 5: Check score guarantee policies and refund eligibility before purchasing
Key Takeaways
- GregMAT ($5/mo) is the best value for self-motivated students needing moderate improvement
- Manhattan Prep and Kaplan live courses ($1,200–$2,500) are worth it for 15+ point improvement needs
- Free ETS PowerPrep tests are essential regardless of which paid course you choose
- The best predictor of GRE success is daily practice consistency — not course price
