TestPrep Advice verdict

GregMat+ is the easiest recommendation in GRE prep.

4.2 / 5

For $11.99 a month — less than a single hour of tutoring anywhere else — you get 10+ live classes a week, structured 1-month and 2-month study plans, nearly 1,000 practice problems, 44 mini-exams, and the Vocab Mountain system students swear by. The platform is basic and the analytics are thin, but at this price the question isn't whether GregMat+ is worth it. It's whether anything else is.

What's included

Live classes

10+ sessions a week with a full archive of recordings, taught in Greg's direct, strategy-first style.

Study plans

Structured 1-month and 2-month plans that tell you exactly what to do each day — the feature students cite most when explaining their scores.

Practice

Nearly 1,000 practice problems, 100+ quizzes, and 44 mini-exams, plus walkthroughs of official ETS PowerPrep questions.

Vocab Mountain & Quant Mountain

Spaced flashcard systems for vocabulary and quant fundamentals.

Tools

A GRE calculator practice tool with timed modes (including accommodation settings), essay tools, and skills checklists for quant and verbal.

PrepSwift (add-on, +$3/month)

Hundreds of short, condensed concept videos for fast review.

Extras

1-on-1 tutoring at $40/hour, private essay feedback for $15 — both cheap by industry standards.

Breakdown by metric

Every product on TestPrepAdvice is graded with the same five-criterion rubric. Each criterion is scored out of 5, and the overall score is the simple average of the five.

1. Question Bank Quality & Accuracy

4.2/5

The bank is smaller than the big brands' — nearly 1,000 problems rather than several thousand — but the quality is high and the teaching leans on official ETS material, with video walkthroughs of PowerPrep questions that show you how the test maker thinks. Student score reports back this up: a published 327 scorer (159V/168Q) credited GregMat's 2-month plan, and 325+ outcomes using GregMat plus official materials are a recurring pattern in student communities. The honest limitation is volume: heavy drillers can exhaust the bank, which is why many students pair GregMat+ with ETS's official Super Power Pack.

2. Platform UX & Interface

3.9/5

Functional, not fancy. The interface is plain compared to premium platforms — no adaptive engine, no AI tutor, no glossy dashboard. What it does well is remove friction: the study plans lay out your day, classes are easy to find live or recorded, and the tools (calculator practice, flashcards, checklists) are one click from the plan. Students describe the experience as no-frills in the complimentary sense — everything is where the plan says it will be.

3. Value for Money

5.0/5

This is the only perfect score we currently award on the site, and it isn't close. GregMat+ is $11.99/month; the PrepSwift bundle is $14.99/month. A two-month plan costs about $24 total. Kaplan and Princeton Review charge several hundred dollars for GRE courses with fewer live hours. There is no contract and you can cancel anytime. For calibration: the GRE itself costs $249 to sit. Your entire prep can cost a tenth of the exam fee.

4. Content Coverage & Depth

4.4/5

Coverage is genuinely complete for a self-study system: full quant and verbal curricula, essay instruction, the 1-month and 2-month plans, and 10+ live classes a week spanning concepts, strategies, and Q&A. Greg's teaching style — strategy over tricks, heavy emphasis on how ETS builds questions — is the product's signature, and the recorded archive means the live schedule is a bonus rather than a constraint. Depth trails the very top end of the market in one place: advanced students hunting the last few quant points may want a specialized quant resource on top.

5. Analytics & Diagnostic Tools

3.4/5

The weakest criterion, and the honest trade-off for the price. You get quizzes, 44 mini-exams, and skills checklists that show what you've covered, but there is no deep diagnostic engine: no per-topic accuracy breakdowns of the kind 7Sage-style platforms produce, no predicted score, no adaptive recommendations. The study plans impose structure from the outside instead — for most students that works, but data-driven self-studiers will feel the gap.

What students say

The pattern across student score debriefs is unusually consistent: students credit the study plans and the Vocab Mountain by name, report scores in the 320s–330s, and express something close to disbelief at the price. Greg himself is a visible presence (he is active in GRE student communities and teaches on the platform), which students read as accountability. Complaints concentrate on the basic interface and the finite question bank.

Who should buy GregMat+ — and who shouldn't

Buy it if

You are preparing for the GRE on any normal budget. Start with the 2-month plan (or 1-month if your date is close), add PrepSwift only if you learn well from short review videos.

Look elsewhere if

You need a huge question bank with deep analytics as your primary system, or you want a score guarantee and a big-brand classroom structure — in which case expect to pay 20–40× more.
