GRE Prep on a College Budget: Free and Low-Cost Resources That Actually Work
The GRE prep industry is not designed for you. Every course and book assumes you have $300 to spare, free evenings, and no competing priorities. You have a class schedule, a part-time job or unpaid internship, recruiting season, and a GPA to protect. The $400 course that works for a 28-year-old analyst does not automatically work for a junior in April.
Here's what does work — and what it actually costs.
The Only Source of Real GRE Questions: ETS Official Materials
Start here before you buy anything else. ETS, the company that makes the GRE, publishes free and low-cost official materials with real test questions. That matters. Every third-party question bank — Magoosh, Princeton Review, Kaplan — is a simulation. The actual test is written by ETS.
Free resources from ETS:
- PowerPrep Online — two full-length computer-adaptive practice tests, free at ets.org. These are the closest thing to the real test you can get without sitting in the testing center.
- Official GRE Practice Questions — a free PDF of sample questions by section type, downloadable from ETS.
The paid ETS options worth considering:
- Official GRE Guide (~$25 on Amazon) — includes two additional full-length tests plus hundreds of practice questions from real tests. At $25, this is the single highest-ROI GRE purchase you can make.
- PowerPrep Plus (~$45 each) — two more computer-adaptive tests with scoring explanations. If you're preparing seriously, one of these is worth the cost.
Total budget if you only use ETS: $0–$70.
The One Paid Tool Worth Adding: Gregmat
If you have $5 to spend, spend it on Gregmat. It's a monthly subscription — cancel after two months and you've paid $10 total.
Gregmat teaches GRE quant strategy through short, focused video modules. The founder runs through concepts the way a good tutor would: triangle rules, number properties, ratio setups, data interpretation traps. It's not exhaustive, but it's targeted. He explains how to think through question types quickly rather than grinding through hundreds of practice problems hoping it clicks.
For verbal, Gregmat's vocabulary system is also useful — he teaches words in semantic groupings rather than random flashcard lists, which helps with retention.
Most students I've talked to who bought a $300 prep course and also used Gregmat said Gregmat was more useful. That's not a knock on Magoosh or Kaplan — it's a reflection of format. Short, conceptual, searchable beats long and comprehensive when you're squeezing prep into a college schedule.
Free Quant Supplement: Khan Academy
If your quant foundation is weak — you haven't taken calculus or stats recently, or you skipped math-heavy courses — Khan Academy fills the gaps for free.
The GRE Quant section tests arithmetic, algebra, geometry, and data interpretation. It does not test calculus. If you're a humanities or social science major who's been avoiding numbers for two years, Khan Academy's middle school and high school math content is the fastest way to rebuild fluency before you start working GRE-specific problems.
Spend one to two weeks on Khan Academy before starting ETS practice problems if you haven't done math in a while. After that, switch fully to GRE-specific materials — Khan Academy is not calibrated to the GRE difficulty level.
Community: r/GRE
The r/GRE subreddit is better than most of what you'd pay for. It has score reports from real test takers, strategy threads broken down by question type, recommendations for free resources, and people at all score levels asking the same questions you have.
Use it for two things:
- Score reports — read posts from people who scored 162–165 on verbal or 165+ on quant and look at what they used. Filter by outcome. Ignore the "I used X course and it was great" posts without a score.
- Specific question strategies — search for the question type that's giving you trouble. Someone has already posted a thread on it.
Don't spend time doomscrolling score comparison posts. Read strategically, then close the tab and do actual practice.
The Real Cost You're Overlooking: The Test Fee
The GRE costs $220+ per attempt (varies by country). That's not nothing. And under ETS policy, you can retake it once every 21 days, up to five times per year.
The implication: if you can't prep seriously before your first attempt, don't take it yet. A mediocre first score isn't fatal — especially with ScoreSelect, which lets you choose which test date's scores you send to schools. But you're still out $220 for a low-value test.
Be honest about your prep readiness before you register. Taking the test when you're 60% ready wastes money. Taking it when you're ready, scoring well, and moving on is the actual goal.
If Your Budget Is Genuinely Zero
Some students are working through school with no discretionary spending. If that's you:
- ETS PowerPrep (free) + the free official practice PDF gets you further than most students realize.
- Your university library almost certainly has GRE prep books — Kaplan, Barron's, Princeton Review — available for checkout. You can use those without buying them.
- Quizlet has free GRE vocabulary decks made by other test takers. The Barron's High Frequency Word List is the most-used; search for it on Quizlet and you'll find multiple free versions.
- Study groups with classmates preparing for the same thing. Working through ETS practice sections together and talking through wrong answers is genuinely useful, especially for verbal reasoning.
The floor is: ETS PowerPrep + ETS Official Guide (library copy) + Quizlet vocabulary + r/GRE. That combination has produced 160+ scorers. It's not glamorous. It works.
What Expensive Courses Actually Sell You
Magoosh, Kaplan, and Princeton Review aren't scams. Their materials are good. What you're paying $300–$500 for is primarily structure and accountability — a pre-built study plan, progress tracking, adaptive drills that adjust to your weaknesses, and the psychological effect of having spent money.
If you need external structure to study consistently, that's worth something. But if you can build your own schedule and stick to it, you don't need to pay for the structure. The underlying content — question types, strategy, vocabulary — is replicable with the free and near-free resources above.
Most college students who build a real 90-day prep schedule around ETS official materials and Gregmat score within three to five points of what they would have scored with a premium course. That's within the margin of a retake anyway.
What Comes After the GRE
Your GRE score gets you over a floor. HBS 2+2 and Stanford GSB admit students with scores in the 160–165 range on both sections — but they also reject students with those same scores. The test is not the application.
Once your score is competitive, your time goes to essays, recommenders, and narrative. That's where the actual outcome gets determined. The students who allocate disproportionate time and money to test prep at the expense of their application story misread what adcoms are actually evaluating.
If you want a clear picture of how the test fits into the full application, read the free module content. If your essays are the priority right now, the essay review service is built for exactly where you are. And if you want direct feedback on your profile and application strategy, reach out about coaching.
The GRE is solvable. You don't need $500 to solve it.
