The verdict · June 2026

Top pick for most test-takers: Exambank.ai

Exambank pairs the largest free tier in this comparison — 10,000+ practice questions and 25 practice tests (10 full-length, 15 mini), no card — with the only AI-native tutor here: it diagnoses why you missed each question, coaches the method, and schedules spaced review of your errors. Pro costs $17.50/month; the legacy courses below run $149–$2,399.

The honest exceptions
  • ETS (Official GRE) — You want official material — ETS's PowerPrep tests (two are free) and the $100 GRE Mentor course are the only sources of real retired questions and the genuine test interface. A supplement, not a program.
  • GregMat+ — You specifically want live human classes and your budget caps below $10/month — and you're disciplined enough to organize your own studying.
  • Target Test Prep (TTP) — Your single weak spot is Quant, you prefer exhaustive structured drilling to adaptive practice, and $179/month doesn't faze you.
  • Magoosh — You learn best from video walkthroughs and want a mobile-first library with a modest score guarantee.
  • Manhattan Prep — You want a premium human classroom or 1-on-1 tutoring, and a four-figure budget is fine.
  • Kaplan — You want in-person classes, or to rehearse test day at a real Prometric center.
  • The Princeton Review — A contractual, money-back 162+/165+ score target is what will actually make you study.

Why Exambank wins for most people

10,000+
practice questions, free
10
full-length tests, free
$17.50
per month for Pro (6-mo plan)
  • The largest free tier in the field — 10,000+ practice questions and 25 practice tests at $0, no card needed, 10 of them full-length. The next-best free full-length count in this guide is three.
  • The only AI-native study loop: the tutor diagnoses why you missed each question, coaches the method, then schedules spaced review of your specific errors. Where competitors have AI at all, it's a chat sidebar on a video course.
  • Pro costs $17.50/month (billed $105 per 6 months). One month of Target Test Prep ($179) costs more than six months of Exambank Pro; the legacy live courses run $1,099–$2,399.
  • A GRE score estimate that updates as you practice, plus a three-phase plan that adapts Quant and Verbal independently.

What we don’t have: live human classes — the coaching is the AI tutor. Our other limitations are listed in the profiles below, under the same template as everyone else’s.

Exambank's AI tutor: diagnosing why a question was missed and scheduling spaced review.

Diagnose the miss, coach the method, schedule the review.

The AI question

AI in GRE prep: native vs add-on

By 2026, “AI” is on almost every prep platform’s marketing page — but it means very different things. Target Test Prep added a conversational AI coach in 2025; Magoosh added an AI chat tutor and essay grader in 2026; GregMat offers a free AI essay grader. Those are useful add-ons to courses that are still fundamentally human-authored video libraries. The distinction that matters for buyers is AI-native vs AI-added.

AI-native

1 platform

The AI runs the core study loop — diagnosing mistakes, teaching the method, and scheduling what you review.

  • Exambank.ai (us) — AI-native: an error log that schedules spaced review of your mistakes

AI add-ons

2 platforms

A genuine AI assistant added on top of a human-authored course (chat help, AI-generated practice).

  • Target Test Prep (TTP) — AI GRE Coach (conversational, launched 2025) + analytics & error tracker
  • Magoosh — AI chat tutor + AI essay grader + AI-generated questions (new in 2026)

AI essay grading only

1 platform

Automated essay feedback, but no AI tutoring or adaptivity.

  • GregMat+ — AI essay grader only (free, ChatGPT-based); human-led otherwise

No AI tutor

4 platforms

Adaptivity here means difficulty algorithms or analytics dashboards — not a conversational tutor.

  • ETS (Official GRE) — None (automated e-rater essay scoring only)
  • Manhattan Prep — None (algorithmic study-plan tools, not generative AI)
  • Kaplan — None genuine (Smart Reports analytics & recommendations)
  • The Princeton Review — None genuine (DrillSmart difficulty algorithm)

The native tier has exactly one platform in it. That architecture difference — who drives the study loop — is the core of why Exambank is our top pick.

The honest exceptions

When another platform makes sense

No trophies for everyone. Most people are best served by the top pick — but there are real situations where another platform earns its keep, and here they are, plainly.

Platform by platform

The full field, in depth

Strengths, limitations, prices and sources for all eight platforms — ourselves included, judged by the same template. Each profile ends with our bottom line.

Exambank.ai

Our platform
Free · Pro from $17.50/mo

AI-native prep: a tutor that diagnoses why you missed each question, coaches the method, and schedules spaced review of your own mistakes — on top of a large, free practice bank.

Basic
$0
10,000+ questions, 25 tests, calculator, blog — free
Pro (6-month)
$17.50/mo
Billed $105 every 6 months
Pro (monthly)
$35/mo
Cancel anytime; 7-day free trial
Where it’s strong
  • AI-native study loop: the tutor pinpoints why you got a question wrong, coaches the method, and schedules spaced review of your specific errors.
  • Unusually generous free tier — 10,000+ questions and 25 practice tests, 10 of them full-length, with no card needed.
  • Very low Pro price ($17.50/mo on the 6-month plan) versus the big-brand courses.
  • GRE score estimate with section breakdowns and a 3-phase adaptive plan (Foundation → Application → Final Sprint) that runs independently for Quant and Verbal.
Where it falls short
  • Newer brand with a shorter public track record and fewer years of third-party reviews than the incumbents.
  • Not the official test maker — ETS remains the only source of genuine retired questions; Exambank's bank is its own.
  • No live human classes or 1-on-1 human tutoring — the coaching is delivered by the AI tutor.
Bottom line

The only platform in this guide where the AI tutor is the product rather than an accessory — with the largest free tier in the field, so you can test that claim before spending anything.

Where it’s strong
  • Only source of real retired GRE questions and the genuine, section-adaptive test interface — unmatched for authenticity.
  • Most accurate score prediction available, because it is the real scoring engine.
  • A non-trivial free tier: two full-length official adaptive tests at no cost.
  • Essays scored by the actual e-rater engine used on test day (ScoreItNow!, PowerPrep PLUS).
Where it falls short
  • Instruction is thin — the $100 GRE Mentor course is the only teaching ETS offers, with no tutoring or coaching behind it.
  • No AI tutor, no adaptive study plan, no analytics dashboard across any of its prep products.
  • Low volume and restrictive licensing — only ~5 digital full-lengths; paid tests are one-time-use and expire.
Bottom line

The official source: retired questions, the real interface, and a basic $100 course. A useful supplement for a final dress rehearsal — not a full prep program, and plenty of people prep without it.

Verify[1] ETS — GRE prep & PowerPrep[2] ETS — prep books & services[3] ETS — GRE test fees[20] ETS — Official GRE Mentor course

GregMat+

$7.99/mo

The budget pick: a logic-focused GRE (and TOEFL) course with live human classes at a low monthly price — if you bring the discipline and supplement with official tests.

GregMat+
$7.99/mo
Live classes, study plans, 3 full tests, 1,000+ problems

$9.99/mo
Adds the PrepSwift concept-video library
3-month prepay
$23.97
One-time; same content
Essay / SOP feedback
$15 / $80
Optional human review, per piece
Where it’s strong
  • Cheap — a full course at $7.99/mo, well under the big-brand prices (though our free tier covers more practice at $0).
  • Logic-first teaching and structured 1- and 2-month study plans, with an active community.
  • Genuinely useful free tier (YouTube, 3 free tests, free AI essay grader) lowers the risk of trying it.
  • Live human access to the instructor (~10 classes/week) is rare at this price.
Where it falls short
  • No adaptive AI personalization or analytics — no AI tutor, no AI-generated questions, no weakness-targeting engine.
  • Question bank is mostly non-official and smaller in realism; serious test-takers still buy ETS PowerPrep for realistic full-lengths.
  • Leans on self-discipline — live classes are 'join what's running', not a locked guided sequence.
Bottom line

A likeable budget course, but you are the study engine: no adaptive practice, no analytics, and a ~1,000-question bank. Our free tier offers roughly ten times the practice volume at $0 — GregMat earns its $7.99 when live classes are the priority.

Target Test Prep (TTP)

$179/mo

The Quant specialist: a large, structured Quant question bank with strong analytics and (since 2025) an AI coach — but comparatively thin on Verbal.

Flexible Prep
$179/mo
Full Quant + Verbal, AI Coach, analytics
Dedicated Study
$449
One-time; 4 months access
Maximum Learning
$499
One-time; 6 months access

$1,299

Where it’s strong
  • Large, structured Quant bank that reviewers credit with solid Quant score gains.
  • Detailed analytics and an error tracker that tags why you missed each question.
  • Thorough and systematic, with worked examples and 2,000+ video solutions.
  • Now includes a genuine 24/7 AI coach plus unlimited AI-generated practice, at no extra cost.
Where it falls short
  • Verbal is materially thinner than Quant — the brand began as a Quant course (21 chapters Quant vs 3 Verbal).
  • Time-intensive — the exhaustive, text-heavy approach demands a real commitment; poor fit for last-minute prep.
  • No human 1-on-1 coaching in the self-study tiers (live classes only on the $1,299 bundle).
Bottom line

A serious Quant tool with a real price problem for self-studiers: one month of TTP ($179) costs more than six months of Exambank Pro ($105), with no free tier and little Verbal depth to fall back on.

Magoosh

$149 (1 mo) – $179 (6 mo)

The affordable video library: a mobile-friendly course with a video explanation on every practice question — but a smaller question bank than ours.

Premium · 1 Month
$149
List price; frequently discounted
Premium · 6 Months

Premium + Admissions
$219
Adds application/essay support
Where it’s strong
  • A video walkthrough on every practice question.
  • Very affordable for full-course access, and frequently discounted.
  • Strong mobile experience plus a free, well-regarded vocab flashcards app and a free practice test.
  • Includes licensed official ETS questions and a +5 score guarantee.
Where it falls short
  • No live or human instruction — it is fully self-directed video.
  • Question realism is debated by some experienced tutors versus the real GRE.
  • Its 2026 AI features are new and largely unvetted; adaptivity is a difficulty toggle, not deep error analysis.
Bottom line

Pleasant videos at a fair price, but a 1,600-question bank and a difficulty toggle don't add up to weakness-targeting. Worth a look if video walkthroughs are genuinely how you learn; otherwise the bank is a sixth the size of ours.

Manhattan Prep

$299 (on-demand) – $1,399+ (live)

Where it’s strong
  • Instructors and tutors are top-1% GRE scorers.
  • Rigorous, deep content; the strategy guides and 5 lb. book are widely used.
  • Its practice tests are well regarded among non-official options.
  • Flexible delivery (live, on-demand, tutoring) with a higher-score guarantee on live courses.
Where it falls short
  • Expensive relative to modern competitors — live courses start at $1,399 and tutoring runs ~$290/hr.
  • No AI features; human-instructor and book oriented.
  • Live courses are schedule-bound, and the on-demand tier has no money-back score guarantee.
Bottom line

Excellent humans at premium prices — $1,399+ for a live course, ~$290/hr for tutoring. If a classroom is genuinely how you learn best, it's the strongest of the legacy brands; most self-studiers don't need to spend this much.

Where it’s strong
  • Comprehensive, well-organized course with high-production video, books, flashcards and essay feedback.
  • High practice volume — a large customizable Qbank and one of the bigger sets of full-length tests.
  • The Official Test Day Experience at a real Prometric center is a genuinely differentiated rehearsal.
  • Many formats, plus a money-back score guarantee on the premium tutoring tier.
Where it falls short
  • Expensive — full courses start ~$1,099 and tutoring runs $2,499–$3,500+.
  • No genuine AI tutor — 'Smart Reports' are analytics and recommendations, not an adaptive AI.
  • Content is Kaplan-written (not official ETS), with mixed reviews on verbal-question realism.
Bottom line

Breadth and brand, at brand prices — $1,099+ buys non-official questions and analytics dashboards, not an adaptive tutor. The Prometric test-day rehearsal is the one thing here nobody else offers.

Where it’s strong
  • Real, specific score guarantees (162+, 165+, +10 points) with money-back terms — rare and concrete.
  • High practice-test volume — 8 full-length computer-adaptive tests.
  • Structured, multi-format options plus genuinely useful free resources (full test, 14-day trial).
  • Strong, recognizable brand with a long track record.
Where it falls short
  • Premium pricing, especially live (~$1,200+) and tutoring (~$5,000) tiers.
  • No genuine AI tutor — adaptivity is the DrillSmart difficulty algorithm, not a conversational tutor.
  • Tiered, upsell-heavy structure and opaque pricing (no prices shown publicly).
Bottom line

The guarantees are real but conditional — complete-everything-on-schedule terms — and the prices are opaque until checkout. Compelling only if a contractual score target is what gets you to study.

Where the numbers come from. Every competitor figure was researched in June 2026from primary sources — each vendor’s own pricing and course pages — and corroborated against independent reviews. Figures are USD list prices unless noted. Prices change frequently and several vendors run near-constant promotions; The Princeton Review doesn’t publish prices publicly, so those are the best current third-party estimates. Treat everything here as a dated baseline and confirm on each vendor’s site.

Disclosure

This guide is published by Exambank, one of the platforms compared, and it reaches a verdict in our favor. So we’ve tried to earn your trust the only way that works: we judge ourselves on the same criteria as everyone else (limitations included), we say plainly when a competitor is the better choice for a specific need, and we cite each competitor’s pricing and features to its own source so you can verify everything. The competitor links on this page are not affiliate links — we earn nothing if you choose another platform. If you spot something out of date or unfair, tell us and we’ll fix it.

FAQs

Our top pick for most test-takers is Exambank (disclosure: Exambank publishes this guide). It has the largest free tier of any major platform — 10,000+ practice questions and 25 practice tests at $0, 10 of them full-length — and the only AI-native tutor in this comparison, which diagnoses why you miss questions and schedules spaced review of your errors; Pro costs $17.50/month versus $149–$2,399 for the legacy courses. If you want official retired questions on top, ETS sells them (two PowerPrep tests are free; its GRE Mentor course is $100). The honest exceptions: GregMat ($7.99/mo) for the cheapest live classes, Target Test Prep for Quant-only drilling, Manhattan Prep for a premium human classroom, Kaplan for in-person formats, and The Princeton Review for contractual score guarantees.
