Why Is My GMAT Score Not Improving?

By charles bibilos

Let’s start with the good news: if your GMAT score has stalled, or even looks like it’s going backwards with more studying, your skills aren’t regressing. There are a handful of reasons why this can happen, and I’ll start with the minor ones before we get to the most likely culprits.

Start by Checking Your Data

Before you panic, take a look at the data you’re pulling that conclusion from.

If you’re working from non-official practice tests or pulling questions from multiple sources, your results are going to bounce around, because those sets aren’t designed to be comparable. You might think, “I was getting 90% of my reading comp right, and now I’m only getting 75%,” and you figure you’re slipping. But if you were doing question sets from completely different resources, that might just be a measurement problem.

This is worth ruling out off the bat. It’s also why we so heavily advocate for official material, because only real, retired questions from GMAC behave like the real test. If you’d like a refresher on what your numbers actually mean, start with GMAT Scoring Explained.

One added nuance: sometimes, even if you use official guide questions, you’ll run into this issue. As you move through official guide sections, the difficulty level increases, but it does so unevenly. Sometimes, a drop in your accuracy just reflects fluctuations in question difficulty from one set to the next, and it isn’t necessarily a sign that your skills are eroding.

You Might Be Studying Yourself Into a Corner

Here’s a sneakier one that happens more than people think: sometimes, the harder you study, the more rigid you get.

If your prep turns into memorizing piles of rules, formulas, and little acronyms invented by a prep company, you can actually get worse at the thing this test is really measuring, which is your ability to reason. We see this often in Quant: a student decides to memorize their way to a great score, then grinds probability and combinatorics for weeks – meanwhile, their Verbal and Data Insights skills are quietly atrophying. 

The worst part? Often, quant isn’t even improving, because the student is training recall instead of reasoning.

So if you’ve been piling on content and your score won’t budge, be honest with yourself: are you actually reasoning through problems, or just trying to remember which rule to apply?

The Real Problem: Execution, Not Knowledge

Usually though, when scores stall, it’s primarily execution.

Students often study, study, then study some more, focusing entirely on content. Their mental checklist goes something like this:

“I learned assumption questions.”

“Now I’ve learned two-part analysis.”

“I picked up this acronym for multi-source reasoning that will help me solve them on the test.”

“I drilled a ton of probability, now I’ve got that down pat.”

This feels great, but there’s one thing missing from this: they’re not paying any attention at all to how they perform once the clock is running, and that’s how they lose points.

The majority of execution problems fit into three main categories:

1. Poor time management. You could know every topic on the GMAT like the back of your hand, but it unfortunately means very little if you’re not able to complete each question on the exam in a timely manner. Either you run out of time, or you’re having to rush to keep up with the clock, both of which lead to mistakes. If this is an issue, check out our time management strategies for the quant and verbal sections of the exam. We also have a video, available here.
2. Careless errors. It’s one thing to know how to do a question, it’s another to be able to do it under exam setting and time pressure. This is where careless errors start to creep in, and these are punished disproportionately on adaptive tests like the GMAT.
3. Test anxiety. Interestingly, test anxiety gets worse over time if left unaddressed, not better. The closer test day gets, the bigger it all feels. If this sounds like you, take our free test anxiety quiz, which helps you understand what potential underlying causes of your anxiety might be. 

Any one of these can make it look like you’re getting worse when you aren’t. Odds are good that your content knowledge is stable or improving, but if your results are getting worse, execution is the real problem. It’s both the most common problem, and also a very solvable one if you’re willing to change your habits and mindset.

So, What Do You Do About It?

First, ignore any data that isn’t truly comparable. Ease off of the rigid formulas and processes, and look at the exam with some flexibility. And start treating timing, careless mistakes, and test-day nerves as things you actively train, not stuff you’ll “figure out on test day”.

Frequently Asked Questions

Can your GMAT score actually go down the more you study?

Yes, on paper. More often than not, you’re comparing inconsistent practice data, leaning too hard on memorization, or running into execution problems like pacing and careless errors. Your actual ability rarely goes backward.

My GMAT score has plateaued. Should I keep studying?

Yes, but change what you’re doing. Once you’ve plateaued, drilling more content usually won’t move the needle much. Shift your focus to execution: pacing, flexible reasoning, accuracy under pressure, and keeping your nerves in check on test day.
