The Most Common GRE Mistakes (and How to Fix Them)

Students read a TC sentence and immediately scan the answer choices. This approach leads to being seduced by plausible-sounding but incorrect options — ETS deliberately designs distractors that sound reasonable in context. Without a prediction, every choice looks defensible.

SE questions require selecting exactly TWO answers that both independently complete the sentence and produce sentences with equivalent meanings. Students often find one strong answer and assume they are done, leaving the second blank unselected or selecting a random second guess.

A common SE trap: students identify two synonyms among the six choices and assume those form the correct pair. But SE requires two words that each independently make the sentence work with equivalent meaning — not simply two words that are synonymous in a dictionary.

Many wrong answers on TC and SE result directly from not knowing the meaning of correct vocabulary words. Without knowing the words, context-clue strategies provide limited protection — you cannot eliminate an answer confidently if you do not understand what the word means.

GRE Reading Comprehension passages range from short (100 words) to long (600 words). Reading every long passage in full before seeing the questions wastes 3–4 minutes per passage on content that may not be tested, causing downstream timing problems.

GRE RC wrong answers frequently include statements that are factually reasonable or intuitively true in the real world but are not actually supported by the specific passage. Students select these because they feel correct rather than because the text directly supports them.

Questions phrased as 'Which of the following is NOT mentioned...' or '...EXCEPT for which...' require identifying the one option that the passage does NOT support. Students frequently misread these as standard questions and select a well-supported answer — the opposite of what is asked.

In 2-blank and 3-blank TC questions, blanks are often logically linked by connectors like 'although,' 'because,' or 'however.' Choosing the wrong direction for one blank (positive vs. negative, agreement vs. contrast) invalidates the entire sentence even if each individual word seems to fit.

QC questions with variables have a classic trap: students test only positive integers and conclude that one column is always larger. But the relationship often reverses for negative values, zero, or fractions. ETS deliberately designs QC questions where the answer depends on the number type.

Numeric Entry questions require an exact answer with no choices to verify against. Students enter intermediate calculation results, forget to simplify fractions, or provide the wrong unit (e.g., entering hours when the question asks for minutes, or entering a ratio instead of a percentage).

The GRE provides a four-function on-screen calculator (addition, subtraction, multiplication, division, and square root). Students use it for every calculation, including simple arithmetic. The calculator interface is slow — entering and computing 3 × 4 takes longer than thinking it, and switching to the calculator breaks problem-solving flow.

Many GRE Quant problems describe geometric configurations in text without providing a figure. Students attempt these mentally and make spatial errors, mislabel angles, or forget which measurement belongs to which element of the figure.

DI passage questions use graphs with non-obvious scales — axes labeled in thousands, logarithmic scales, or with unusual intervals. Students read values directly from the visual without checking units, producing answers that are off by a factor of 1,000 or more.

Students confuse permutations and combinations, apply the multiplication rule where the addition rule applies, or treat dependent events as independent. Probability and combinatorics questions appear on every GRE Quant section but are often under-prepared because students avoid them.

GRE Quant includes Multiple Answer questions requiring you to select all correct answers — there may be one, two, three, or more. Students frequently select only the most obvious correct answer and leave additional valid options unselected. Partial credit is not awarded — all correct options must be selected.

GRE word problems frequently ask for something other than what you naturally solve for during calculation: the value of x + 2 rather than x, the remaining amount after a deduction rather than the total, the percentage change rather than the new amount, or the combined rate rather than an individual rate.

Many AWA responses cite general concepts ('history has shown...', 'studies suggest...', 'experts believe...') without naming a specific event, person, study, or example. The e-rater and human graders both favor specific, concrete evidence. Vague support produces band 3–4 scores regardless of essay structure.

Students describe or summarize the Issue or Argument rather than analyzing it. A summary says what is claimed; an analysis examines why, interrogates underlying assumptions, evaluates evidence quality, and considers implications and counterarguments. Summaries score at band 3.

AWA Issue essays score highest when they demonstrate intellectual complexity and awareness of counterarguments. An essay that only argues one direction and treats all objections as obviously wrong signals limited analytical thinking and scores below band 5 even with good examples.

The thesis — your clear position on the Issue — should appear as the final sentence(s) of your introduction paragraph. Many essays bury the thesis in the third body paragraph, state it vaguely ('it depends'), or omit it entirely in favor of extended context-setting. Without a clear thesis, the essay seems unfocused and structurally weak.

AWA essays under 350 words almost always score band 4 or below, because there is insufficient space to develop a complex argument with multiple supporting points, specific evidence, counterargument acknowledgment, and a conclusion. Short essays signal inability to sustain analytical writing.

The Argument Analysis task (formerly 'Analyze an Argument') requires identifying logical flaws in a provided argument — unwarranted assumptions, flawed analogies, hasty generalizations, insufficient evidence. Students who treat it as an Issue essay (arguing their own opinion) score very low.

Body paragraphs that launch directly into an example without a topic sentence force the grader to infer what argument the paragraph is making. This produces an essay that feels disorganized even when the content is relevant and specific.

Many students deprioritize AWA because the 0–6 score is reported separately from the Verbal and Quant composite. However, many graduate programs — especially in humanities, social sciences, law, and policy — set explicit AWA minimums (commonly 3.5–4.5) and use AWA as a direct measure of writing and reasoning ability.

Students leave hard questions blank or guess randomly without first attempting to eliminate options. On any 5-choice Verbal question, eliminating one wrong answer improves your odds from 20% to 25%; eliminating two raises it to 33%. Even partial elimination meaningfully improves expected score across a full section.

GRE Verbal sections have 41 minutes for 27 questions (~91 seconds average per question). Quant has 47 minutes for 27 questions (~104 seconds average). Students who spend 3–4 minutes on one difficult question often find themselves rushing through the final 5–6 questions with under a minute each, producing preventable errors.

The GRE allows you to return to any question within a section and change your answer before time expires. Research on standardized tests consistently shows that second-guess changes are wrong more often than right on questions where the original choice was made with genuine reasoning rather than pure guessing.

The GRE is section-adaptive: your performance on Verbal Section 1 determines whether you receive an easier or harder Verbal Section 2 (same for Quant). Harder Section 2 questions award access to the highest score ranges. Students who cruise through Section 1 without full effort can trap themselves in an easier Section 2 that caps their achievable score.

The GRE typically includes one unscored research section (Verbal or Quant) that does not count toward your score but appears identical to scored sections. There is also an identifiable unscored section in some formats. Students either panic trying to identify which section is unscored (wasting energy) or give up on a section they wrongly believe is unscored.

Students often spend disproportionate study time on the hardest question types (e.g., 3-blank TC, QC with unusual number properties) while neglecting medium-difficulty questions that appear more frequently in scored sections. Missing three medium questions costs more than missing one hard question.
