You scored a 320 on the GRE. You're watching M7 medians hover around 325-328, and you're wondering if the problem is the test itself. Maybe you'd perform better on the GMAT. Maybe the verbal section is dragging you down and the GMAT quant would play to your strengths.
At 320, the answer is almost never to switch.
How Close You Actually Are
The programs you're targeting are not as far as they look. Darden's GRE median is 322. Haas sits at 323. Kellogg is 324. Wharton is 325. You are 2 to 5 points away from being at the median of programs ranked in the top 10.
Booth and Columbia sit at 326. HBS and Stanford are at 328. That's 6 to 8 points away. Still not a mountain.
A 5-point improvement on the GRE means getting 2 to 3 more questions correct per section. That is not a fundamental gap in ability. That is a prep gap. The difference between a 320 and a 325 is the difference between going in cold and going in with a focused six-week study plan.
What Switching Tests Actually Costs You
A GRE 320 converts to roughly an old GMAT 620-650. For context, old GMAT 700 converts to GMAT Focus Edition 645. You are not sitting on equivalent scores across formats. Switching tests means starting over.
There is no official GRE-to-GMAT Focus concordance. Admissions committees understand this, which is exactly why they do not expect you to convert. They accept both tests at face value.
When you switch, you spend the first 3 to 4 weeks just learning the new format: the question types, the scoring system, the section timing, the adaptive logic. That is time you could have spent turning a 158 into a 163. By the time you sit for the GMAT, you are a novice on a different test competing against applicants who have studied it for months.
The Only Reason to Switch
There is one scenario where switching makes sense. If you have genuinely hit a ceiling on GRE verbal due to vocabulary and you have spent months working on it, not weeks, then the GMAT verbal section's different format might play better for you. GMAT verbal does not test vocabulary the way GRE verbal does. It focuses on logical reasoning, which is a different skill.
But this is rare, and the honest version of this scenario sounds like: you have done 8 to 10 full practice tests, you have studied vocab systematically for 3 months, and your verbal score still sits at 155 or below. If that is not you, it is not the ceiling scenario. It is a prep scenario.
How to Read Your 320 Breakdown
Your score breakdown changes the prep strategy, not the test choice.
If your split is 158V/162Q, verbal is the gap. That means vocabulary and reading comprehension practice. Closing 5 points on verbal is very achievable with consistent work. The GRE verbal section rewards the vocabulary prep you have not yet done.
If your split is 162V/158Q, quant is the gap. Focused math review on the specific concept areas the GRE tests most: algebra, geometry, data interpretation. A 158 to 163 on quant is a tractable problem.
If your split is 160V/160Q, both sections need 2 to 3 points. That is the most common 320 breakdown, and it is the clearest case for retaking. You are not weak in any one area. You are close everywhere. Four to six weeks of structured prep will move both numbers.
How to Prep for the Retake
The TDMBA GRE course is $25 per month and built for exactly this scenario: you have already taken the test, you know your score, and you need to close a specific gap. The course includes 19,000+ practice questions, concept lessons for every quant and verbal topic, a vocabulary system for the 1,200 most tested GRE words, and a diagnostic that tells you where your points are hiding.
The diagnostic alone is worth doing before you touch another practice problem. It maps your accuracy by topic and surfaces the 3 to 5 areas where you are losing the most points. Most 320 scorers are not weak everywhere. They are losing 4 points in one quant topic and 3 points in one verbal category. Fix those, and the score moves.
Other courses like Magoosh and Manhattan Prep are solid options if you prefer video-heavy content. The TDMBA course is the stronger choice if you want question volume and want to study at your own pace without paying $400 to $500 upfront.
Programs That Accept 320 as Competitive
Before you prep for anything, it is worth knowing what 320 already gets you. Darden's Early Decision program, Haas's Deferred Enrollment Program, and Yale SOM's Silver Scholars all have medians within 3 to 5 points of 320. Applicants below the median get admitted every cycle.
The stat is one piece of the application. A 320 with a 3.9 GPA, a strong leadership story, and a specific reason for deferring reads very differently from a 325 with a generic profile. Do not over-index on the test.
That said, if your application is strong everywhere else and the test is the one thing holding it back, the retake is worth it. You are starting from 320, not from zero. The score is already there. The prep is about closing a gap you have already mostly closed.
Action Steps
-
Pull your score report and look at the section breakdown. Note your exact V and Q scores. This determines your study plan, not your total score. See our guide on how to read your GRE diagnostic baseline.
-
Do a targeted diagnostic before starting any prep. The TDMBA diagnostic maps your accuracy by topic so you know exactly where your points are. Start there, not with a full practice test.
-
Build a 4 to 6 week study plan focused on your weaker section. If you are within 3 points of your target score on one section, defend it with one session per week and put everything else into the gap section. See our guides on GRE verbal reasoning and GRE vocabulary strategy.
-
Take one full practice test at the halfway point to calibrate. Rerun the diagnostic after. The goal is to confirm the gap is closing, not just to practice.
-
Register for the retake when your practice tests hit 323 or above. Do not wait for a 327. Book the test when you are scoring in range, then treat the last week as sharpening, not learning.

You are 5 points away from median at multiple top-10 programs. That is 2 to 3 questions per section. The GRE course was built to find exactly those points: 19,000+ practice questions, a free diagnostic that maps your weaknesses by topic, concept lessons for every tested area, and a full vocabulary system. $25 per month. The playbook's test strategy module covers how to make the test decision based on your full profile. For a direct read on your specific situation, coaching is where that conversation happens.
