GMAT vs GRE: Which Test Should You Take?

Neither exam is harder, and neither score converts into the other. The GMAT runs 2 hours 15 minutes for 64 questions, which works out to 29 percent more time per question than the GRE, while the GRE runs 1 hour 58 minutes and gives you a calculator for every quant question.

So the decision is not about prestige. It is about your school list first, then pacing, then whether you want that calculator.

Key takeaways

• The GMAT is 2 hours 15 minutes with 64 scored questions. The GRE is 1 hour 58 minutes with 54 scored questions plus a 30 minute essay.
• Per question, the GMAT is the slower, roomier exam: 2 minutes 7 seconds against 1 minute 38 seconds on the GRE.
• The GRE gives you an on-screen calculator throughout Quant. The GMAT gives you one only in Data Insights, never in Quant.
• Both testmakers state that GRE and GMAT scores cannot be converted. Every conversion chart online is unofficial.
• At a US test center the GMAT costs $275 and the GRE costs $249, a $26 gap per attempt.

The specs that actually differ

Most comparisons stop at total length. That is the least useful number of the set, because the two exams package their time very differently.

Current published structure of both exams. Source: GMAC and ETS, read September 2026.

The GMAT is three 45 minute sections: Quantitative Reasoning with 21 questions, Verbal Reasoning with 23, and Data Insights with 20. You choose the order, and one optional 10 minute break sits between sections.

The GRE is five sections with no break. Analytical Writing comes first and always takes 30 minutes. Then two Verbal sections of 12 and 15 questions, and two Quant sections of 12 and 15 questions.

That structural difference drives the money too. The GMAT costs $275 at a US or Canadian test center and $300 online, while the GRE is $249 either way. Note that the GMAT has no writing section on the exam, so if a program wants a writing score you book a separate 30 minute GMAC writing assessment for $30.

The GRE is shorter overall, but the GMAT gives you more time per question

Strip out the GRE essay and the pacing picture inverts. The GRE gives you 88 minutes for 54 scored multiple-choice questions. The GMAT gives you 135 minutes for 64.

Calculated from each testmaker's published section timings. GRE figures exclude the 30 minute essay.

Every GMAT section is slower per question than every GRE section:

Overall that is 2 minutes 7 seconds per GMAT question against 1 minute 38 seconds per GRE question, a 29 percent difference. On quant alone the GMAT gives you 23 percent more time, and on verbal 29 percent more.

Read that against the calculator rule and you get the real trade. The GRE gives you a calculator and less time. The GMAT gives you more time and no calculator. If mental arithmetic under pressure is your weak point, the GRE removes the problem outright. If you think slowly but accurately, the GMAT pays you for it.

Calculator, adaptivity, and how many answers you can change

Three mechanics separate these exams more than any content difference.

The calculator. The GRE provides an on-screen calculator for Quantitative Reasoning. The GMAT provides one in Data Insights only, and none at all in Quantitative Reasoning, where you get note boards and markers.

Adaptivity. The GMAT adapts question by question, so each item is chosen from how you answered the last one. The GRE adapts section by section: your performance on the first Verbal section sets the difficulty of the second.

Changing answers. This follows directly from adaptivity. On the GRE you can skip around and change as many answers as you like inside a section. On the GMAT, the Question Review and Edit screen at the end of each section lets you review freely but change at most three answers.

That three-answer cap is the detail most people learn too late. It means flagging six questions on a GMAT section is pointless, and it makes first-pass accuracy worth more on the GMAT than on the GRE. Our guide to how hard the GMAT really is goes deeper on what that pressure feels like.

There is no GMAT score equivalent to a GRE score

This is the most searched question in the comparison, and the answer is not a number. Both testmakers say the conversion does not exist.

On its own GRE vs GMAT page, linked in the section above, ETS puts it in one line: it does not publish a score conversion table for the two exams. GMAC is blunter, publishing a dedicated page stating that you cannot convert a GRE score to a GMAT score, and vice versa.

The charts you find online mostly trace back to one source. ETS hosted a GRE comparison tool for business schools for over a decade, and it no longer sits on the ETS website. Other sites copied the chart before it went, which is why it still circulates.

GMAC's head of test development and psychometrics, Chris Han, published the reasons it was withdrawn. The tool was built on a small, self-reported, unrepresentative sample collected 12 years ago, before either exam was redesigned. It carries no data points at all for Data Insights, which is one of the three equally weighted sections of your GMAT Total Score.

The error bars are the part worth remembering. ETS footnoted the tool as accurate to about plus or minus 50 points, but that figure was a 68 percent confidence interval, and the underlying standard error was 54.8 rounded down.

For scale, the GMAT's own measurement error sits around 30 to 40 points across the range, including above 700. A conversion estimate five times wider than the exam's own error is not a planning tool.

Note the contrast with a conversion that is official. GMAC does publish a concordance between the current 205 to 805 scale and the older 200 to 800 GMAT, and our GMAT score conversion tool runs on that table. There is simply no equivalent for the GRE.

What to compare instead of converted scores

Both testmakers point at the same replacement, which is unusual given how hard each one argues for its own exam: compare yourself to the programs you are applying to, not to the other test.

Two things are worth checking.

Your percentile on the test you took. A GMAT Focus 655 sits at the 90th percentile, with 705 at the 98th and 605 at the 69th, against a pool of 509,182 test takers from 2021 to 2026. For the GRE, run your sections through our GRE score and percentile calculator, which uses the current ETS reference window.

The median score of your target class. Most business schools publish the median GMAT and GRE scores of admitted students. That number tells you something a conversion chart never can, because it is specific to the programs you actually care about.

One caution on percentiles: they are not interchangeable either. The GMAT pool is business school applicants, while the GRE pool spans every graduate field. The 60th percentile in one is not the 60th percentile in the other.

Which exam should you take

Work the decision in this order.

Start with the school list. Confirm what each program accepts and whether it asks for a writing score. Nearly all business schools take both now, so this step usually clears quickly, but it is the only step that can rule an exam out.

Then take one timed section of each. Not a full test. One GMAT Quant section and one GRE Quant section, timed honestly. You will learn more in 92 minutes than from any comparison article, including this one.

Choose the GMAT if you want more time per question, you reason well without a calculator, and you are applying only to business schools. Its Data Insights section has no GRE counterpart, and it signals a committed business school applicant.

Choose the GRE if you want a calculator in Quant, you are also applying to non-business graduate programs, or you want the flexibility to move freely within a section. The built-in writing section also saves you the separate $30 assessment if a program requires a writing score.

Once you have picked, the prep decision comes next. Our GMAT prep course roundup ranks the main options, Target Test Prep being the one we rate highest for quant-heavy studying, and our review methodology explains how we test them. The GMAT hub and GRE hub collect the tools and guides for each exam.

GMAT vs GRE FAQs

What is harder, GRE or GMAT?

Neither is objectively harder, and the two make opposite demands. The GMAT gives you 29 percent more time per question but no calculator in Quant and only three answer changes per section. The GRE is faster paced, at 1 minute 31 seconds per verbal question, but lets you use a calculator and revise freely within a section.

Does Harvard prefer GMAT over GRE?

Harvard Business School lists the requirement on its application process page as "GRE or GMAT" and states no preference between them. Other programs handle it the same way, but policies are set school by school, so confirm with each program on your list rather than assuming.

What is a GMAT score equivalent to a GRE score of 320?

There is no official equivalent, and neither testmaker publishes one. ETS does not even publish a percentile for the combined Verbal plus Quant total that a 320 represents, and GMAC estimates that predictions from the old conversion tool could be off by 200 points at the GMAT 650 level. If a site gives you a single number for a 320, it is using a withdrawn chart built on 12 year old self-reported data.

Is a 307 a good GRE score?

It depends entirely on the split, which is why combined GRE totals mislead. On the current ETS reference data behind our GRE percentile calculator, a 307 built from 153 Verbal and 154 Quant puts you at the 54th percentile in Verbal but only the 34th in Quant, and business schools read the quant number closely. Check the median GRE scores your target programs publish before deciding whether to retake.
