Bad information about the GRE spreads fast. It gets shared in study groups, repeated on forums, and baked into advice that has not been updated in years. Acting on wrong information can cost you months of misdirected preparation or lead you into decisions that hurt your application.
These are the 10 most common myths, where they come from, and what is actually true.
Myth 1: The GRE Is Question-Adaptive
This one shows up constantly, and it is a meaningful distinction. The GRE is section-adaptive, not question-adaptive.
Question-adaptive means each individual question changes based on your answer to the previous question. That is not how the GRE works.
Section-adaptive means your performance in Section 1 determines which version of Section 2 you receive: a harder set or an easier set. Within each section, every test taker gets the same questions in the same order. The adaptation happens between sections, not between questions.
Why does this matter? Because it changes your strategy. You cannot "unlock" harder questions by getting early questions right within a section. What you can do is perform well in Section 1 overall to route into the higher-difficulty Section 2, which gives you access to a higher scoring ceiling.
Myth 2: Superscoring Exists for the GRE
Superscoring means taking the highest Verbal score from one attempt and the highest Quant score from another attempt and combining them into a single composite score. Many students believe this is standard practice for the GRE.
ETS does not superscore the GRE. Each test attempt produces a single Quant score and a single Verbal score, and those scores are reported as a pair from that sitting. There is no official process by which the highest Quant from attempt 1 is combined with the highest Verbal from attempt 2 to create a new composite.
Some individual programs claim to take the highest section score across attempts when building their internal evaluation. This is program-specific and informal, not a standardized ETS policy. Do not build your retake strategy around the assumption that superscoring will apply. Aim to hit your target on a single sitting.
Myth 3: Business Schools Prefer the GMAT Over the GRE
This used to be approximately true. It is no longer accurate for most programs.
The shift has been gradual but substantial. As of recent admissions cycles, the majority of top MBA programs explicitly state they consider both exams equally. Many have removed any GMAT preference language entirely. Among the top 54 MBA programs tracked by ETS, 17 report receiving more GRE applicants than GMAT applicants.
The practical implication: if you perform better on the GRE, submit the GRE. If you genuinely do not have a preference, look at the specific programs you are targeting and check their published data on admitted students. A handful of programs still have small but detectable GMAT preferences in practice. Most do not.
The era of the GMAT as the "serious" business school exam is over for most applicants.
Myth 4: You Need 6 Months to Study for the GRE
Six months is far more than most people need and can actually hurt your preparation if the extra time creates fatigue or diluted focus.
The realistic preparation window for most test takers is 6 to 12 weeks of consistent, structured studying. Students who start from a strong academic baseline (recent math coursework, strong reading background) often do well with 6-8 weeks. Students who are rusty on quantitative material or have not done serious academic work recently may need closer to 10-12 weeks.
What six months of preparation often creates: a slow start, inconsistent momentum, and burnout in the final weeks when you most need to be sharp. The students who score highest tend to study with concentrated intensity over a shorter period rather than spreading work thinly over months.
Take the diagnostic early. It tells you exactly where your gaps are and how much work each area needs. Build a study plan around the actual gap, not an arbitrary timeline.
Myth 5: Harder Practice Questions Produce Better Results
The logic seems sound: if you train on hard questions, the real exam will feel easier. In practice, it backfires.
The GRE has a specific distribution of difficulty. Most questions on any given section are in the medium range. Training exclusively on hard questions skews your calibration. You start expecting hard questions, missing medium questions because you are overcomplicating them, and developing anxiety about difficulty that the real exam does not actually deliver at that frequency.
More importantly, practice questions that are harder than GRE-level but not calibrated to GRE-style thinking can train wrong strategies. The GRE rewards specific reasoning patterns and has a distinctive question construction style. Questions that push difficulty by deviating from that style train you for something other than the real exam.
Train on realistic difficulty distributions. The goal is to match what you will see on test day, not to exceed it.
Myth 6: Scoring 170Q Is the 99th Percentile
This is a common misread of the percentile tables. A 170 on Quant is currently around the 91st percentile, not the 99th.
The Quant score distribution is heavily compressed at the top because many test takers score in the 160s. A score of 165 is only the 67th percentile. The 99th percentile in Quant would require a nearly perfect score in a population where top scores cluster tightly.
Verbal has different distributions. The 99th percentile in Verbal is typically around 169-170, and scores in the 160-165 range sit in the high 80s to mid-90s percentile range.
Understanding the actual percentile distributions matters for target-setting. If a program says it admits students at the 90th percentile in Quant, that is approximately a 165, not a 170. Calibrate your target to the actual data.
Myth 7: Schools See Every Time You've Taken the GRE
This is false. ETS's ScoreSelect policy gives you control over which scores are sent to programs.
You can choose to send scores from a specific test date only, from all attempts within the last 5 years, or from your most recent attempt. Programs only see what you choose to send. They do not have access to a comprehensive testing history unless you choose to send it.
The practical implication: there is no penalty for taking the exam, performing poorly, and retaking it. You report only the score you want reported. This makes strategic retaking much more viable than many students assume, and it removes the fear of "ruining" your application by having a low score on record.
Keep in mind that some programs explicitly ask how many times you have taken the GRE on their application forms, even if ETS does not send all scores automatically. Answer honestly on those forms.
Myth 8: The GRE Calculator Handles Complex Math
The GRE provides a calculator, but it is a basic four-function calculator with a square root button. It does not do trigonometry, logarithms, statistical functions, or anything beyond arithmetic.
The implication is that questions requiring complex computation are not present on the GRE, because the calculator does not support them. Questions that look complex are either (a) solvable by reasoning and estimation without heavy calculation, or (b) require arithmetic that the basic calculator can handle.
Students who expect to rely on a calculator for difficult Quant questions find themselves stuck, because the real challenge is not the arithmetic. It is setting up the problem correctly and applying the right mathematical reasoning. A calculator does not help with that.
Myth 9: AWA Score Matters Significantly for MBA Admissions
The Analytical Writing Assessment (AWA) is scored on a 0-6 scale and is reviewed for MBA applications, but its importance is dramatically lower than Quant and Verbal.
For most MBA programs, AWA functions as a threshold score rather than a differentiating factor. The general understanding is that a score of 3.5 or above is considered acceptable, and anything above 4.0 is effectively treated the same way. Admissions committees are primarily looking for evidence that you can write coherent, organized arguments. They are not ranking applicants based on AWA scores above the threshold.
Where AWA matters is at the floor: a score of 3.0 or below can raise questions about writing ability, particularly for applicants whose undergraduate institution is not known for rigorous writing instruction or whose first language is not English.
Prepare enough to clear the threshold confidently. Do not divert significant study time from Quant and Verbal to chase a perfect 6 on AWA.
Myth 10: You Cannot Significantly Improve Your Verbal Score
This myth persists partly because Verbal improvement feels slower and less tangible than Quant improvement. In Quant, you learn a formula and you can apply it. In Verbal, progress feels diffuse.
But Verbal scores are highly improvable with the right approach. Vocabulary does move the needle, particularly on Text Completion and Sentence Equivalence. Strategy is even more important on Reading Comprehension, where most score ceilings are not set by vocabulary but by reading approach: students who read for general understanding pick wrong answers that are technically consistent with the passage but do not answer the specific question asked.
The students who improve Verbal the most are the ones who study both vocabulary and question strategy together, rather than treating them as separate tracks. Knowing a word helps you nothing if you are eliminating the correct answer for the wrong strategic reason.
Full-length mock exams are particularly useful for diagnosing Verbal performance patterns because they give you the complete Verbal experience under real time pressure, including the passage-heavy Reading Comprehension sets in Section 2 that are harder to simulate in short practice drills.
Verbal is improvable. The ceiling is not set by aptitude. It is set by the quality of your preparation.
The common thread in all ten myths is that they come from real sources, partial truths, or outdated information that has calcified into conventional wisdom. Check your assumptions against current data. Build your preparation around what the GRE actually is, not what people say it is.
