When Should You Take the GRE®? Working Backward From Deadlines
Two instincts shape how people pick a GRE® test date. The first says study first and book when the practice scores look ready, because a booking adds pressure to a process that already has plenty of it. The second books the date right away, and lets the deadline drive the study schedule. Both instincts make sense, and both half-work, which is why the same question keeps turning up in test-prep forums: how do you know when you're ready, and is it too late to test before your deadline?
Start with the reassurance: if your deadline is still months away, you probably have room. Scores stay reportable for five years, the test itself runs about 1 hour and 58 minutes, and ScoreSelect® means an attempt you don't like can stay private. How much room depends on the gap between your baseline and your target and the hours you can give each week, which is exactly what the backward math is for. A GRE® score isn't usable on the day you take the test: official scores post to your ETS account 8 to 10 days later, per ETS, sends process on top of that, and the retake spacing adds weeks if attempt one falls short. The test date is the last link in a chain, and the way to place it is working backward from the deadline.
The backward method: four dates to find
In this method the application deadline is the anchor, and every other date gets derived from it, in reverse.
First, find the deadline. Round 1 MBA deadlines typically fall in September, Round 2 in early January, and many PhD programs set their deadlines in December and January; some Master's programs run on rolling admissions instead. These windows move from program to program, so the deadline to work from is the one printed on each program's admissions page, not a rule of thumb.
Second, find the score-arrival date. Per ETS, official scores, including Analytical Writing, are typically available in your ETS account 8 to 10 days after your test date. On test day you can designate up to four institutions or fellowship sponsors to receive your scores as part of the test fee, and requests to send scores take approximately 5 business days to process. Budget about three weeks from test day to the school's file, and a few days of slack on top. A score that arrives after the deadline may not be considered under that program's process, which is the risk the buffer exists to prevent.
Third, find the retake date, if you want one. ETS lets you retest every 21 days, up to five times in any continuous rolling 12-month period. Spacing makes a retake possible, but it doesn't make the retake prepared, and our retake framework spends four questions on the difference. For calendar purposes, the first attempt needs to sit far enough before the last-acceptable test day that a day-22 retake could still send scores in time, with whatever prep weeks the gap requires.
Fourth, find the prep start. The distance between a baseline score and a target, converted to hours and divided by your weekly study time, gives the length of the prep window; our guide to study length walks through that math and why "2 to 3 months" is a guess until you've run it. One provenance note we keep attached to the numbers: the planning estimates come from our GMAT® study-time dataset, rescaled through the score-scale difference between the two tests, and climbs that start near 340 can cost roughly twice the mid-band rates.
Run those four dates in a row and the test date becomes a calendar decision instead of a readiness feeling, which is also what makes the plan adjustable when one of the inputs changes.
A worked example: a Round 2 application
Take a Round 2 deadline in early January and run the math backward.
Scores need to reach schools by the deadline, so the last test day worth booking sits about three weeks earlier, in mid-December, once you account for the 8-to-10-day posting window, the send processing, and some slack. That much follows straight from the ETS timelines. The retake layer sits on top of it: a second attempt 21 days before mid-December lands in late November, and its scores should still arrive in time. The first attempt then belongs around late October or early November, close enough to the retake that the diagnosis stays fresh but far enough that the in-between weeks can be real prep.
The prep window comes from the gap. Suppose the baseline is 305 and the target is 315. For the illustration, assume the climb splits evenly, five points in each section. At the mid-band planning estimate of about 25 hours per section point through self-paced course materials, that's around 125 hours, which at 12 hours a week is about ten weeks. Ten weeks before late October is August, and the estimate is a planning number, not a forecast; a baseline practice test can move it in either direction.
So the chain reads: start in August, test in late October, retake (only if the first attempt says so) in late November, and the schedule should put scores in schools' hands about a month before the deadline. The same math run against a Round 1 deadline in September slides everything back about four months. A January start to studying tends to leave more room for a September deadline, while a June start can mean choosing between a rushed September date and a January Round 2, depending on the gap and the weekly hours.
PhD and Master's deadlines move the same way
The same method works across program types, with the dates adjusted to each program's rules. A December 15 PhD deadline pulls the last test day into late November, the prepared-retake window into early November, and the first attempt into early October, about two weeks earlier at every link than the Round 2 example. Programs with January or February deadlines stretch the chain back out.
One caution is specific to this stretch of the calendar: the weeks between late November and early January include holidays that can slow a study schedule down, and that's a reason to protect the buffer rather than trim it. If your deadline sits in that window, consider leaving one extra week of slack between the last test day and the deadline itself.
Why an earlier date is usually the safer default
Two ETS policies make testing earlier than you "need" to a low-risk move.
Scores stay reportable for five years, so an attempt taken well before you apply keeps its value across application cycles. And ScoreSelect®, available on test day or any time you order reports, means a result you don't want a committee to see doesn't have to reach one: per ETS, on test day you can send nothing at all, or choose for each of your four free reports either your most recent attempt or all attempts from the last five years. Additional Score Reports (US$40 each) can be ordered any time in that five-year window and add an "Any" option that picks specific attempts. Our ScoreSelect guide covers the fine print, including the programs that ask for all attempts.
The earlier date has a preparation benefit too. A booking converts "I should study for the GRE® sometime" into a date the study plan, the practice test schedule, and the final-week plan can all hang from. Open-ended timelines tend to drift; a booked date gives the plan a fixed point.
Booking logistics worth knowing
Registration happens through an ETS account, and the GRE® General Test registration fee is $249 USD globally, with the exception of China at $231.30, per ETS. You can test at a center or at home; our at home vs test center guide walks the tradeoffs in detail. One at-home step matters for late bookers: identity verification through ETS's IDVaaS app needs to be completed at least 72 hours before the appointment, per ETS, so a last-minute at-home booking compresses the runway for that step.
Check the current reschedule and cancellation fees when you book, and it's reasonable to plan for the possibility that the date moves once. Prep schedules rarely run exactly to plan, and a booking you can adjust is easier to keep.
FAQ
When should I take the GRE® for fall admission?
Work backward from the program's deadline. For Round 1 MBA deadlines in September, a first attempt by late spring leaves room for a prepared retake with scores arriving well before the deadline; for Round 2 deadlines in early January, first attempt by late October or early November; for PhD deadlines in mid-December, first attempt by early October. The general rule: book the first attempt at least two months before the deadline, and earlier whenever the prep math requires it.
How long after the GRE® do schools receive scores?
Official scores are typically available in your ETS account 8 to 10 days after your test date, per ETS. The four reports you designate on test day go to institutions as part of the test fee, and requests to send scores take approximately 5 business days to process, so budget about three weeks from test day to the school's file.
How late can I take the GRE® before an application deadline?
About three weeks is a conservative planning floor: 8 to 10 days for scores to post, approximately 5 business days for send processing, and several days of slack. A test booked closer to the deadline than that risks arriving after the committee has reviewed your file, so leave more room whenever the calendar allows.
Can I retake the GRE® before my deadline?
Yes, if the calendar allows. You can retest every 21 days, up to five times in any continuous rolling 12-month period, and a retake's scores follow the same 8-to-10-day posting and processing timeline as any attempt. That means the retake needs to happen at least three weeks before the deadline, and the attempt before it 21 days before that.
Should I book the test date before I start studying?
Booking first works well when it comes with a prep plan, because the date anchors the study calendar. The date to book is one your backward math supports: deadline, minus score-arrival time, minus a retake buffer, minus the prep window your baseline-to-target gap requires.
Do I have to send GRE® scores right after the test?
No. On test day you can send nothing at all, or use your four included reports on your most recent or all attempts, and Additional Score Reports (US$40 each) can be ordered any time in the five years your scores stay reportable, per ETS.
