How Hard Is the GRE? Average Scores, Section Difficulty & What Students Say

The GRE has a reputation as a challenging exam, but the nature of that challenge varies dramatically by your academic background. A humanities PhD candidate and a computer science master's student may approach the same test and find entirely different sections difficult. This guide breaks down what the data actually shows about GRE difficulty and what you can realistically expect.

1. What Makes the GRE Hard

The GRE is hard for different reasons than the SAT. Whereas the SAT primarily tests reasoning with grade-level content, the GRE adds:

Graduate-level vocabulary. The GRE Verbal section uses words like "tendentious," "sanguine," "laconic," and "perspicacious" — academic vocabulary that most college graduates haven't actively encountered. This is an intentional test of the vocabulary expected in graduate-level reading.

Reasoning under time pressure. GRE questions require multi-step reasoning — not just "what is the answer" but "what is the relationship between these quantities, and what does that imply?" The time pressure makes this harder.

Adaptive difficulty. If you perform well in Section 1, Section 2 is harder. For students targeting 160+, the hard Section 2 is genuinely difficult — not just SAT hard, but Graduate Record Examination hard.

Longer academic stamina. The GRE rewards sustained attention across a nearly 2-hour testing window. Fatigue affects performance, especially in the later sections.

2. Average Scores and Score Distribution

Verbal Reasoning

| Scaled Score | Approximate Percentile | |---|---| | 170 | 99th | | 165 | 96th | | 160 | 86th | | 155 | 67th | | 151 | ~50th (average) | | 145 | 26th | | 140 | 12th |

Quantitative Reasoning

| Scaled Score | Approximate Percentile | |---|---| | 170 | 96th | | 166 | 87th | | 160 | 76th | | 155 | 59th | | 153 | ~50th (average) | | 148 | 34th | | 140 | 11th |

Important nuance: Quant percentiles are compressed at the top because many test-takers (especially those from STEM backgrounds) score very high on Quant. A 165 on Verbal places you in roughly the 96th percentile; a 165 on Quant places you in approximately the 87th percentile. The distributions differ because the Quant-competitive population skews heavily STEM.

What This Means in Practice

For competitive graduate programs, the relevant comparison is not to the general test-taker population but to your specific applicant pool. If you're applying to a top-5 CS program where 60% of admitted students score 168+ on Quant, a 160 is relatively weak — regardless of what percentile it represents among all GRE takers.

3. Verbal Reasoning: Why It's Hard

The GRE Verbal section is widely considered the hardest for students without extensive academic reading backgrounds. There are three primary sources of difficulty:

Advanced Vocabulary (Text Completion and Sentence Equivalence)

These questions test words that are genuinely uncommon in daily usage but appear regularly in academic literature. Many students encounter 5–10 words per section they've never seen before.

This is learnable — but it requires deliberate vocabulary study, not just reading more. A targeted list of 500–1,000 high-frequency GRE words, studied with spaced repetition, can meaningfully improve performance on these question types.

Dense Reading Passages

GRE reading passages are drawn from real academic publications — sciences, humanities, social sciences. They use complex sentences, specialized terminology, and layered arguments. Unlike the SAT, where passages are simplified for a high school audience, the GRE doesn't simplify.

Students who don't regularly read academic texts often report that processing these passages under time pressure is their biggest challenge.

"Tricky" Wrong Answers

GRE wrong answers are carefully constructed to be plausible. On Reading Comprehension questions, the wrong answers often:

• Address something in the passage but not what the question asked
• Are too extreme (absolute language like "always" or "never" when the passage is more nuanced)
• Are true but irrelevant to the question's specific focus

Distinguishing correct answers from plausible-but-wrong answers requires careful reading and a systematic approach to evaluating each choice.

4. Quantitative Reasoning: Why It Surprises Students

Many students assume GRE Quant is easy because "it's just high school math." This is partially true and very misleading.

The Content Is High School Level

The GRE Quant covers arithmetic, algebra, geometry, and basic statistics — nothing beyond pre-calculus. There's no calculus, no linear algebra, no differential equations.

The Reasoning Is Graduate Level

The difficulty isn't the content — it's the application. GRE Quant questions require:

• Multi-step reasoning with abstract variables
• Setting up the right mathematical framework for a word problem
• Recognizing which mathematical relationship a problem is testing
• Handling questions with multiple correct answers or answers of "cannot be determined"

Students who are strong mathematicians but haven't done this type of algebraic reasoning recently often find their skills are rustier than expected.

The Time Pressure Is Real

With 21 minutes for 12–15 questions, you have approximately 85–105 seconds per question. Many problems that are straightforward with unlimited time become challenging when you need to solve them efficiently under pressure.

What STEM Students Get Wrong

STEM students often underestimate Quant difficulty and under-prepare. Then they encounter Quantitative Comparison questions designed to trip up students who make implicit assumptions (like assuming all variables are positive integers). These traps catch STEM students who "know the math" but haven't studied the specific reasoning patterns the GRE tests.

5. Analytical Writing: The Overlooked Section

AWA is the section students spend the least time preparing for — and it shows in average scores (~3.6/6.0).

Why It's Difficult

• Writing a coherent, well-developed argument in 30 minutes requires practice
• The Issue and Argument tasks require specific rhetorical moves that differ from college essay writing
• Many students write responses that are too short, not specific enough, or use imprecise language

Why It Matters Less Than Verbal and Quant

For most programs, AWA is a threshold score — programs typically want to see 3.5–4.0 as a minimum, and anything above 4.5 is strong. Very few programs weight AWA heavily in their decisions. The exception is programs where writing is central to the discipline (literature, journalism, philosophy).

Why It's Hard to Improve Significantly

AWA scores above 5.0 require sophisticated argumentation, linguistic precision, and command of formal writing conventions that take time to develop. Students who aren't strong academic writers can improve modestly with practice but rarely see dramatic gains.

Realistic targets: If you write well in academic settings, aim for 4.5–5.0. If you haven't done substantial formal writing recently, 4.0–4.5 is an achievable target with 2–3 weeks of structured practice.

6. How Section Adaptivity Affects Difficulty

The GRE's section-level adaptation means:

Students routed to hard Section 2: Will face genuinely challenging questions — passages with subtle argumentation, Quant problems with abstract reasoning requirements, vocabulary that's uncommon even among graduate students. This is where scores above 160 are determined.

Students routed to easy Section 2: Face more accessible questions but have a lower score ceiling. You can still score well within the accessible range (~145–155) regardless of performance, but 160+ requires the hard track.

The psychological effect: Many students are surprised by the jump in difficulty in Section 2 if they performed well in Section 1. This surprise can cause panic. Understanding that a hard Section 2 is a good sign — not a sign of failure — is important mental preparation.

7. How the GRE Compares to the SAT

Students who took the SAT in high school often ask how it compares to the GRE.

| Feature | SAT | GRE | |---|---|---| | Target population | High school students | College graduates | | Vocabulary level | Accessible, context-dependent | Advanced academic vocabulary | | Math level | Through pre-calculus basics | Through pre-calculus, more abstract reasoning | | Reasoning complexity | Moderate | Higher | | Writing | None (essay discontinued) | 1 essay task (30 min) | | Test duration | ~2 hr 14 min | ~1 hr 58 min | | Score scale | 400–1600 | 260–340 combined | | Adaptive type | Question-level | Section-level |

The GRE Verbal section is significantly harder than the SAT Reading/Writing section, primarily because of vocabulary demands. The GRE Quant covers similar content to the SAT Math but applies it with more abstract reasoning. The overall experience is more intellectually demanding but shorter in duration.

8. What Graduate Students Say After Taking It

Based on forums like Reddit's r/GRE, GradCafe, and prep community surveys, common student reports include:

"The vocabulary killed me." Verbal is consistently cited as the section that surprises students most — particularly those from STEM backgrounds who expected to compensate with Quant.

"Quant was harder than I expected." Even math-proficient students are caught off guard by Quantitative Comparison questions, which require careful reasoning rather than just computation.

"I ran out of time in Verbal." The pacing on GRE Verbal is tight. Reading comprehension passages take more time than expected, leaving less time for Text Completion and Sentence Equivalence.

"The AWA wasn't as bad as I thought." Students who prepare at least modestly for AWA (writing a few practice essays) typically find the actual test manageable.

"Section 2 of Verbal was brutal." Students routed to the hard Verbal track frequently report that Section 2 felt like a different test entirely.

9. Can Preparation Significantly Improve Scores?

Yes — but the ceiling and rate of improvement vary.

Quant: High Improvement Potential

Students who haven't used algebra in several years often see dramatic Quant improvements with targeted review. Gains of 8–15 points are common with 6–12 weeks of focused practice. Students starting at 145–155 can often reach 160–165 with systematic study.

Verbal: Moderate Improvement Potential

Vocabulary acquisition takes time but is highly learnable. Students who study 500+ high-frequency GRE words consistently see Verbal improvements. Reading Comprehension improves with practice on GRE-specific passages. Gains of 5–10 points are common; 10–15 points is achievable with longer preparation.

AWA: Low Improvement Potential (Short-Term)

AWA scores above 4.5 require developed writing skill that takes time to build. Students can improve 0.5–1.0 points with structured practice. Dramatic AWA improvements (2.0+ points) are uncommon without significant investment.

Combined Gains

Most students who study systematically for 8–16 weeks see 10–20 total point improvements in their combined Verbal + Quant score. Students who start significantly below their target scores may need longer timelines.

FAQ

Q: Is the GRE harder than the GMAT? A: They test different things. GMAT is considered stronger in quantitative reasoning for business contexts; GRE Verbal may be harder for students without strong academic vocabulary. The right comparison is which test matches your strengths.

Q: Can you fail the GRE? A: There's no pass/fail. Every test-taker receives a score. Programs set their own competitive thresholds.

Q: What's a perfect GRE score? A: 170 Verbal + 170 Quant + 6.0 AWA. This is exceptionally rare.

Q: Is a 310 GRE score good? A: It depends on the field and program. For competitive programs in STEM (where Quant matters most), 310 composite may be below average. For social work or education programs, 310 is often competitive. Context matters.

Q: Is the GRE getting easier over time? A: The 2023 shortened format reduced test length but didn't change difficulty. The scoring algorithm adjusts for form difficulty, so a "shorter" test isn't inherently "easier" on the score scale.

Q: Do all grad programs require the GRE? A: No. Many programs eliminated the GRE requirement post-pandemic. Verify current requirements for each program you're applying to.

The Honest Assessment

The GRE is genuinely challenging — designed to differentiate among college graduates applying to competitive academic programs. But it's also highly learnable. Unlike content-heavy exams where you need to memorize years of accumulated knowledge, the GRE tests a finite set of skills and vocabulary that can be systematically acquired.

Students who start early, study their specific error patterns, and use official practice materials consistently improve. The question is not whether you can improve — it's whether you give yourself enough time and use the right methods to do so.
