GRE Quant Hub: Concepts, Strategies, and Targeted Practice (By Topic)

Quant now appears in two adaptive sections that total 27 questions across 47 minutes: Section 1 has 12 questions in 21 minutes; Section 2 has 15 questions in 26 minutes. The test remains section-level adaptive: your performance in Section 1 influences the difficulty of Section 2. You can skip, mark, and return within a section, and an on-screen calculator is provided. There are no scheduled breaks; at test centers you may take an unscheduled break but the clock keeps running, and at-home testing does not allow unscheduled breaks. You’ll see unofficial Quant and Verbal scores on screen if you choose to report; official scores post about 8–10 days later. No partial credit is awarded, and there’s no penalty for wrong answers—so never leave anything blank.

This hub gives you a practical roadmap: what to know (concepts by domain), how to think (strategies by question type), and where you’ll lose points (timing, traps, and careless errors). It also includes targeted practice menus—short, focused sets you can plug into any schedule. If you study with Exambank, map each section below to a Playbook and let your AI tutor build sessions that mix Learn → Solve Together → Test Yourself, so you’re always drilling exactly what moves your score.

GRE Quant samples high-school level math and introductory statistics—no calculus or trigonometry. Expect a blend of four domains: Arithmetic (fractions, ratios, percents, rates, exponents, roots, absolute value, number properties), Algebra (expressions, equations/inequalities, systems, functions, coordinate geometry), Geometry (angles, triangles including 30-60-90 and 45-45-90, circles, polygons, 3D, area/volume; figures not drawn to scale), and Data Analysis (descriptive stats such as mean/median/SD/IQR/percentiles, data interpretation, probability, counting with permutations/combinations, Venn diagrams, and basic normal distributions). Question types: Quantitative Comparison, multiple choice single answer, multiple answer (select all that apply), numeric entry, and data interpretation sets.

Average time is about 1 minute 45 seconds per question. Use a two-pass plan in each section: Pass 1 (Now) solve quick wins in ~45–90 seconds, guessing as needed and marking tricky ones. Pass 2 (Later) revisit marks with a clear cutoff: if you aren’t making progress after ~60 seconds, make your best educated guess and move on. Build a 60–90 second buffer for the final three minutes to sweep flagged items and ensure nothing is left blank.

Timing: over-investing in a single problem, failing to guess-mark-move. Traps: precise misreads (units, inclusive/exclusive counts, integer constraints), attractive wrongs (intermediate results, wrong variable, off-by-one), and Quantitative Comparison pitfalls (testing only one case). Careless errors: sign slips, copying mistakes, mismatched units, rounding when exact values are required, or selecting the right number to the wrong question. Each domain below pairs high-yield knowledge with specific fixes for these failure modes.

Concepts to master: ratios and proportions, percent change vs. “percent of,” unit-rate thinking, exponents/roots rules, absolute value, divisibility, LCM/GCD, remainders, and sequences. High-frequency traps: mixing base value vs. change, treating rates like totals, and ignoring integer constraints. Playbook focus: Ratio Tables and Unit Ladders (for clean setups), Percent Triangles (to separate base/part/change), and Remainder Scenarios (small-case testing mod n). Targeted practice: 15–20 item sprints that alternate percent/ratio word problems with number-property items; finish with 3–4 numeric-entry questions to tighten precision.

Concepts to master: translating words to equations, linear/quadratic forms, inequalities and absolute value, systems (elimination/substitution), and function basics (domain, piecewise, composition). Traps: forgetting to flip inequality signs when multiplying or dividing by negatives, losing track of restrictions after squaring or taking roots, and solving for the wrong variable. Playbook focus: Equation Blueprints (templates for distance/work/mixture), Backsolving and Smart Plugging (using answer choices or simple numbers to stress-test the setup), and Restriction Checklists (domain/denominators/radicals). Targeted practice: 20–25 mixed Algebra items with 8–10 word problems; time-box each setup to 60 seconds before any algebraic grind.

Concepts to master: triangle similarity, special triangles, circle arc/sector relationships, polygon interior/exterior angles, area/volume, coordinate slope-intercept-distance-midpoint, and parallel/perpendicular lines. Traps: assuming drawings are to scale, misusing diameter/radius relationships, or mixing linear vs. area scale factors. Playbook focus: Similarity Ladders (AA and side ratios), Area-Volume Scale Rules, and Coordinate Quick-Checks (slope/product tests, distance without formula via Pythagorean triples). Targeted practice: 12–15 problems in two waves—pure diagram reasoning first, then coordinate cleanup—to reinforce translating visuals into equations.

Concepts to master: mean vs. median behavior, the effect of outliers on center and spread, weighted averages, quartiles/IQR, boxplots and scatterplots, and when to use the complement rule in probability. Counting foundations: slots, permutations with repeats, combinations, and simple Venn overlaps. Traps: mixing independent vs. mutually exclusive, misreading multi-axis charts, and double-counting in arrangements. Playbook focus: Read-Then-Compute protocol (units first, what the question wants second, then arithmetic), Complement First for “at least” problems, and Structured Counting (write the slots; label; fill; divide). Targeted practice: one 5–6 question data set plus 5 probability/counting items; finish with two normal-distribution estimations.

QC rewards structured testing, not gut feeling. Start by simplifying/algebra when it’s obvious. If not, pick numbers that honor every constraint, and challenge the relationship with edge cases: zero, one, negatives, fractions between 0 and 1, and very large values. Look for symmetry and hidden factorization to compare without full solving. Frequent trap: testing only one “nice” number and concluding too fast. Playbook focus: The Five-Case Drill (0, 1, fraction, negative, large), Constraint Sticky Notes (copy integer/positive/distinct to your scratch), and When to Declare “Relationship Cannot Be Determined.” Targeted practice: 12–15 QC items in short bursts with a 60-second cap per attempt.

Multiple answer questions require every correct choice and no wrong choices—partial credit doesn’t exist. Numeric entry often demands exact values; read any rounding instructions carefully. Playbook focus: Answer-Choice Hygiene (test each option independently; don’t stop after finding one that works) and Exactness Habits (keep fractions until the end, avoid premature rounding, and confirm units). Targeted practice: 10 mixed items with a strict “units and rounding” checkpoint before submission.

Use the calculator to offload tedious arithmetic, not thinking. Keep expressions symbolic until the final step; estimate first to catch keystroke slips; and memorize the usual suspects (common fraction–decimal conversions, squares up to 25, cubes up to 10). Avoid chained rounding; store intermediate results if needed. Playbook focus: Mental Math Anchors, Calculator Last, and Estimation Sandwiching (compute a bracket to sanity-check the exact value).

Section 1 (12 questions, 21 minutes): 14 minutes for Pass 1, 5 minutes for Pass 2, 2-minute sweep. Section 2 (15 questions, 26 minutes): 17 minutes for Pass 1, 7 minutes for Pass 2, 2-minute sweep. In both sections, guess immediately on time-traps, mark them, and move; returning with fresh eyes beats burning three minutes mid-section.

Run PARSE before you submit: Prompt asks for? (exact/approx, units, which variable). Assumptions copied? (integer/positive/distinct). Rough-check? (order of magnitude, sign, parity). Scan the choices? (did you pick a decoy like the intermediate value or the complement). Exactness? (fraction vs. decimal, rounding). Build this as a literal two-line checklist at the top of each scratch page.

• Arithmetic Speed Set: 12 questions, mixing percent/ratio and unit-rate word problems; goal ≥ 10 correct in 18 minutes.
• Algebra Setup Lab: 10 translation items + 6 systems/inequalities; goal is clean setups under 60 seconds.
• Geometry Core: 8 similarity/triangle + 6 circle/area; finish with 2 coordinate slope/distance.
• Data Pack: one 5-question data set + 5 counting/probability.
• QC Burst: 12 questions using the Five-Case Drill.
• Precision Pack: 8 numeric entry + 6 multiple answer with strict exactness rules.

Because the second section’s difficulty responds to how you did in the first, your goal is high accuracy with strict time caps early, not perfection at any price. Protect your first section with disciplined triage, then lean into your strengths in Section 2. Finishing every section and answering every question is non-negotiable.

Four hours/week plan: 1) Diagnostic refresh (30 minutes) to set targets; 2) Two domain sessions (45 minutes each) using a Playbook plus a Solve Together walkthrough; 3) One mixed-practice hour that includes a QC Burst; 4) 30-minute review building your mistake log and flashcards. Eight hours/week plan: Double the domain sessions, add a full timed section (47 minutes) every weekend, and run one Precision Pack midweek to eliminate rounding/units slips.

Each entry captures the question ID, topic, failure mode (timing, trap, or careless), root cause (e.g., misread units, skipped restriction, algebra slip), and a new rule you’ll apply next time. Tag entries so Exambank can auto-build your next review set and resurface the pattern when it reappears in fresh questions.

Start with the diagnostic; your AI tutor will map strengths and weak points to the domain Playbooks. In Learn, you’ll refresh the exact concept you missed; in Solve Together, you’ll work step-by-step through a GRE-style problem while the tutor checks setup and reasoning; in Test Yourself, you’ll get short, adaptive quizzes that reinforce without burning time. As you practice, Exambank tunes difficulty to push edges without wrecking accuracy and builds personalized review stacks from your mistake log. The analytics view shows accuracy by topic, time per item, and predicted score trajectory so you see what’s improving and what still needs work.

• Timing & Triage Playbook (two-pass method for 12+15 sections).
• Arithmetic Speed & Accuracy Playbook (percents, ratios, unit ladders).
• Algebra Setup Playbook (translation templates, backsolving, restrictions).
• Geometry & Coordinate Mastery Playbook (similarity, area/volume scale, slope-distance).

• Calculator Control Playbook (estimation sandwiching, calculator-last).
• Careless-Error Immunity (PARSE checklist, exactness habits).

Warm up with 3–5 quick problems before you start; hide the clock until the last five minutes if it spikes anxiety; write your PARSE checklist at the top of your first scratch page; triage aggressively; answer every question; and trust your training—especially on QC and data sets, where method beats hunches.

The shorter GRE raises the premium on clarity, setup, and time discipline. Master the four domains, neutralize the three failure modes, and practice in focused, bite-size blocks. With a strong triage routine, exactness habits, and targeted drills, you’ll convert more work into points—consistently.
