How Hard Is the GRE?

The GRE is moderately difficult. It ranks harder than high school tests but easier than other standardized exams.

The GRE lasts under two hours, with 54 scored questions and one essay, making it shorter than most other standardized exams (which can run up to 7.5 hours). Its adaptive format makes questions more difficult if you perform well in the first section. Common pain points include dense vocabulary, tricky multi-step math word problems, and time crunches on reading passages.

What Are the Time Constraints on the GRE?

What Are the Time Constraints on the GRE

There are three parts of the GRE: Verbal Reasoning, Quantitative Reasoning, and Analytical Writing.

Verbal Reasoning splits into two sections: 12 questions in 18 minutes, then 15 questions in 23 minutes. 

Quantitative Reasoning also splits into two sections: 12 questions in 21 minutes, then 15 questions in 26 minutes. 

Analytical Writing gives you 30 minutes for a single essay. 

These sections work out to roughly 90 seconds per Verbal Reasoning question and 1 minute 45 seconds per Quantitative Reasoning question.

However, Reading Comprehension passages and multi-step word problems routinely take twice as long. Every question you overspend on forces you to rush somewhere else. And rushing on the GRE produces more wrong answers than strategic guessing would. 

Build pacing into every practice session from day one. Knowing the material means nothing if you can't deploy it within the time window.

What Topics Does the GRE Cover?

The GRE tests a mix of math, reading, vocabulary, and writing skills commonly used in graduate-level education. Its content covers these core areas:

  • Algebra, geometry, arithmetic, and data analysis: Quantitative Reasoning focuses on foundational math concepts, including equations, ratios, percentages, probability, graphs, and interpreting charts and tables.
  • Reading comprehension: Tests your ability to analyze complex passages, identify arguments, and draw logical conclusions from academic-style writing.
  • Text completion and sentence equivalence: Tests vocabulary, context clues, and verbal reasoning by asking you to complete sentences using the most logical word choices.
  • Analytical writing: Requires you to write a structured essay to test your ability to evaluate an argument and communicate your ideas clearly under time pressure.

Most students have at least one area that needs improvement. For pre-med students, Quantitative Reasoning gaps usually surface around ratios, coordinate geometry, and probability. 

Verbal Reasoning is where science-focused students lose the most confidence. The passages read like condensed academic journal articles covering the humanities and social sciences. This can be a jarring shift if you've spent college reading biology textbooks and research protocols.

GRE vs. MCAT: Exam Difficulty, Structure & Strategy Differences

Infographic comparing GRE vs. MCAT

The GRE and MCAT test very different skills, and most students find the MCAT significantly harder overall. The GRE measures general academic reasoning used across many graduate programs. The MCAT tests advanced scientific knowledge, passage-based reasoning, and mental endurance specific to medical school admissions.

GRE vs. MCAT Difficulty

Most students can prepare for the GRE in two to three months. MCAT preparation often takes three to six months because the exam covers far more material and requires deeper scientific analysis.

The MCAT is also much longer. The GRE takes about 1 hour and 58 minutes, while the MCAT lasts roughly 7.5 hours with breaks. Many students describe the MCAT as both a content exam and an endurance exam.

GRE vs. MCAT Content Differences

The GRE focuses on:

  • Vocabulary and reading comprehension
  • Algebra, geometry, and data analysis
  • Analytical writing

The MCAT tests:

  • Biology and biochemistry
  • General and organic chemistry
  • Physics
  • Psychology and sociology
  • Critical reasoning through dense scientific passages

Unlike the GRE, the MCAT rarely rewards simple memorization alone. Students must apply concepts across multiple disciplines within passage-based questions.

Strategy Differences

Scoring high on the GRE requires mastering test patterns, timing, and core math/verbal skills. MCAT success requires long-term content mastery, stamina, and the ability to interpret complex research-style passages under pressure.

The exams also differ in retake flexibility. Students can take the MCAT up to three times in a single calendar year, while the GRE can be taken up to five times within a rolling 12-month period.

Here’s a summary of the major differences between the GRE and the MCAT:

Category GRE MCAT
Primary Purpose Graduate school admissions Medical school admissions
Typical Test-Takers Master’s, MBA, PhD applicants Pre-med students applying to MD/DO programs
Exam Length About 1 hour 58 minutes About 7 hours 30 minutes
Main Subjects Tested Verbal reasoning, quantitative reasoning, analytical writing Biology, biochemistry, chemistry, physics, psychology, sociology, critical reasoning
Question Style More direct and skill-based Passage-heavy and analytical
Difficulty Level Moderate Very high
Study Timeline Usually 2-3 months Often 3-6+ months
Mental Endurance Required Moderate Extremely high
Retake Limits Up to 5 times in a rolling 12-month period Up to 3 times in one calendar year
Common Challenges Vocabulary and timing Scientific reasoning and stamina

FAQs

Is the GRE Hard Without Studying?

The GRE is significantly harder without studying because the test is designed to exploit exactly the kind of overconfidence that unstudied test-takers bring to the table. The math covers concepts you learned in high school, but most students haven't actively used algebra or geometry in years, and ETS builds trap answers that punish anyone relying on vague recall instead of sharp fundamentals. 

How Hard Is It to Prepare for the GRE?

Preparing for the GRE is hard but possible. Most test-takers need one to three months of preparation. The difficulty depends almost entirely on the gap between your baseline score and your target.

Does the GRE Have a Lot of Math?

Yes, about half of the GRE has math. Quantitative Reasoning accounts for 27 of the 54 scored questions, split across two separately timed sections (12 questions in 21 minutes, then 15 in 26 minutes). 

What Is the Most Difficult Part of the GRE?

Most students struggle with Verbal Reasoning the most. Specifically, the dense, humanities-heavy Reading Comprehension passages and the sophisticated vocabulary tested in Text Completion and Sentence Equivalence questions make up roughly half the Verbal section.

How Hard Is It to Get a 300 on the GRE?

A score of 300 on the GRE is an achievable goal for many test-takers, as it represents an average score. The GRE is scored on a scale of 260-340, with 130-170 points possible for both the Verbal Reasoning and Quantitative Reasoning sections.
