The GRE has been under two hours since September 2023, and the way most people study for it has not changed at all. Here is how to study for the GRE using what memory research actually shows works, what the 2026 test looks like, and an 8-week plan you can start today.
The short version
Most GRE prep is rereading, highlighting, and watching videos. In the largest review of study techniques ever published, those methods were rated low utility. The two methods rated high utility were practice testing and spacing your study over time (Dunlosky et al., 2013). Interleaving problem types, especially for math, roughly doubles the benefit over 30 days compared with drilling one topic at a time (Rohrer, Dedrick and Stershic, 2015).
So the plan below is built on three moves: test yourself instead of rereading, spread it out instead of cramming, and mix problem types instead of blocking them. CoChat helps you do the first two faster. It does not take the test for you.
What the GRE looks like in 2026
If your last exposure to the GRE was a friend’s horror story from 2019, the test has changed. All of the following comes from ETS’s official pages as of September 2026.
| Analytical Writing (one “Analyze an Issue” task) | 1 essay | 30 min |
| Verbal Reasoning, section 1 | 12 | 18 min |
| Verbal Reasoning, section 2 | 15 | 23 min |
| Quantitative Reasoning, section 1 | 12 | 21 min |
| Quantitative Reasoning, section 2 | 15 | 26 min |
| Total | 54 questions + 1 essay | 1 hr 58 min |
Details that change how you prepare:
- No unscored section, no scheduled break. The shortened format that took effect September 22, 2023 removed both. Stamina still matters, but the test is now a sprint, not a marathon.
- One essay, not two. The “Analyze an Argument” task is gone. You only prepare for “Analyze an Issue,” and ETS publishes the full pool of possible topics.
- Section-adaptive. The second Verbal and Quant sections are harder or easier depending on how you did on the first. Early accuracy earns you a harder, higher-ceiling second section.
- You can skip and return within a section, and Quant gives you an on-screen four-function calculator.
- Scores. Verbal and Quant run 130 to 170 in 1-point increments; Analytical Writing runs 0 to 6 in half-point increments. Official scores arrive in 8 to 10 days and stay valid for 5 years. ScoreSelect lets you choose which test dates a school sees: four score reports are free on test day (most recent or all), and additional reports cost $40 each afterward.
- Cost and retakes. The fee is $249 USD effective August 1, 2026. You can retake once every 21 days, up to five times in any rolling 12-month period. Rescheduling costs $55. If you qualify for the ETS Fee Reduction Program (FAFSA Student Aid Index of 0 or below, unemployment in the past 6 months, Peace Corps service, or programs such as TRIO and McNair), the test is $100 and comes with about $100 of official prep material. A retake is not a failure; it is a second data point.
- At home or in a center. The test is offered 365 days a year at more than 1,000 test centers in 160+ countries and at home. The at-home version has required a second camera (a phone or tablet on a stand) since January 5, 2026, and ETS tightened ID verification for all sessions booked on or after March 31, 2026, so read the current ID rules before you register.
One more thing worth knowing before you commit eight weeks: in a 2022 ETS/NAGAP survey of 167 graduate admissions professionals, 38% said tests were optional and 36% said they were not required at all, and policies have kept moving since. Check each program on your list. Optional does not mean ignored: in a December 2025 Manhattan Prep/Kaplan survey, 75% of test-optional business programs said a competitive score still gives applicants an edge, and ETS reports that 87% of applicants who submit GRE scores to test-optional programs are accepted (self-selection does some of that work, so treat it as encouragement, not a guarantee). If your practice scores are strong, send them; if they are weak, the time may be better spent on your statement.
What the research says about how to study for the GRE
The GRE rewards two things that are learnable in eight weeks: a working vocabulary of several hundred words you do not currently use, and fast, accurate recall of high-school math you have not touched in years. Both are memory problems, and memory research is unusually clear about what works.
1. Test yourself. Do not reread.
A meta-analysis of 61 experiments found that testing yourself instead of restudying produced a mean effect of d = 0.50 on later retention, and when the practice test came with feedback the effect rose to d = 0.73 (Rowland, 2014). A second meta-analysis of 272 effect sizes across 188 experiments put the advantage of practice testing over restudy at g = 0.51, and at g = 0.93 over doing nothing; when the practice test came 1 to 6 days before the final test, the advantage grew to g = 0.82 (Adesope, Trevisan and Sundararajan, 2017). That last number is the case for a practice test in the final week.
For the GRE: every review session should start with a question, not a page. Flashcards, timed sets, and closed-book recall of formulas all count. Reading the answer explanation after you attempt the problem is the feedback that pushes the effect from 0.50 toward 0.73.
2. Space it out. Do not cram.
Across 317 experiments, spaced study produced 47.3% recall versus 36.7% for massed study, and when the test came 8 to 30 days later the gap widened to 62.2% versus 32.8% (Cepeda et al., 2006). That second number is the one that matters for a test you take weeks after you learn the material.
The vocabulary-specific version of this finding used GRE-type word pairs. Students who cycled through one big stack of flashcards outperformed students who split the same cards into four small stacks and studied each one intensively. Spacing won for 90% of participants, yet 72% of them predicted, after the first session, that the small-stack method was working better (Kornell, 2009). Cramming feels productive. That feeling is the bug.
3. Mix problem types. Do not block them.
In a three-month classroom study, students who practiced mixed sets of math problems outscored students who drilled one problem type at a time, with d = 0.42 on a test the next day and d = 0.79 on an unannounced test 30 days later (Rohrer, Dedrick and Stershic, 2015). The reason is simple: on the real test, nobody tells you “this is a geometry question.” Interleaving trains you to recognize the problem type, which is half the work on GRE Quant.
Where CoChat fits (and where it does not)
CoChat is a research workspace, not a test-prep company, and this post is not affiliated with ETS. It fits GRE prep in exactly the places the research above points to: generating retrieval practice from your own materials and scheduling it over time.
| Learn 500+ vocabulary words | Space one large deck, test yourself, get feedback | Build a flashcard deck from your word list; the deck runs on spaced repetition and exports to Anki if you prefer to review on your phone |
| Relearn formulas and rules | Retrieval with feedback beats rereading | Upload your math notes to a Project and ask CoChat to quiz you on them, one question at a time, with the explanation after you answer |
| Practice mixed Quant sets | Interleave problem types | Ask for a 12-question mixed set drawn from your notes across arithmetic, algebra, geometry, and data analysis, then check your work against ETS’s official Math Review |
| Practice the Issue essay | Write under time, then get specific feedback | Draft your 30-minute essay yourself, paste it in, and ask for a critique against the ETS scoring criteria. You write every word; the feedback is the point |
| Keep everything in one place | Consistency over 8 weeks | One Project holds your word deck, notes, practice-test scores, and error log |
What CoChat will not do: it is not a source of official GRE questions, it does not replace ETS’s POWERPREP practice tests, and asking it to write your practice essays defeats the only purpose of writing them. Use official ETS material for anything that needs to look like the real test. Use CoChat to practice recalling what you learned from it.

The 8-week plan
Assumes 8 to 10 hours per week. Every week starts with retrieval, not reading.
Week 1: Baseline. Take POWERPREP Practice Test 1 (free from ETS) under real conditions, at home, no breaks. Record section scores and every missed question in an error log. Build your first flashcard deck from the words you did not know in the Verbal sections. Download the ETS Math Review PDF and note which chapters felt foreign.
Weeks 2 to 3: Foundations, spaced. Vocabulary: 20 new cards a day into one deck, reviewed by the spaced-repetition schedule; never split the deck. Quant: work through the Math Review chapters you flagged, but end every session with 10 mixed problems drawn from all chapters covered so far, not just today’s. Writing: read the ETS Issue topic pool and outline three essays, no drafting yet.
Weeks 4 to 5: Interleave everything. Vocabulary continues (you should be near 300 cards). Quant sessions are now fully mixed sets, timed at roughly 1 minute 45 seconds per question, which is the pace the real sections demand. Write one full 30-minute Issue essay each week, then critique it against the ETS scoring criteria. Update the error log after every set and quiz yourself on the log itself once a week.
Week 6: Second practice test. POWERPREP Practice Test 2, timed. Compare to Week 1 by section. Whatever moved least gets 60% of your time for the next two weeks. If your Quant first section was strong but the second was weak, the problem is stamina and pacing, not content; do more full-length timed sections.
Week 7: Weakness sprint. Vocabulary reviews only (no new cards). Quant: mixed sets limited to your two weakest topics plus a random third. One more timed essay. Book your test if you have not, and if testing at home, set up and test the second camera now, not on test morning.
Week 8: Taper. Light retrieval every day, nothing new. Reread nothing. One short mixed Quant set and 15 minutes of flashcards per day is enough. Two days out, stop. Sleep.
If your Week 6 score is more than a few points below your target in either section, remember the retake policy: 21 days between attempts, five per year. A second sitting six weeks later, with a plan built on what the first one revealed, is often the higher-return move.
Start with one deck
The highest-return hour you can spend today is not reading a prep book. It is taking the free POWERPREP test, pulling out every word you did not know, and turning those words into one flashcard deck you will review every day for eight weeks. That single habit uses both of the techniques the research rates highest, and it is the one 72% of students talk themselves out of.
