GRE Quant: Question Types & the Comparison Trick

Quantitative Comparison, multiple choice, numeric entry and data interpretation — school-level maths, tested cleverly.

The big picture

The maths is basic — the traps aren't

GRE Quant covers arithmetic, algebra, geometry and data analysis at roughly high-school level. The difficulty is in careful reading and avoiding traps, not advanced maths. An on-screen calculator is provided, so speed comes from setup, not arithmetic.

💡
Real example: A question looks like it needs heavy computation but is really testing whether you noticed 'x is negative' — the trap rewards the reader, not the fastest calculator.
🧠 Memory hook: Easy maths, sneaky wording. Read twice, compute once.

Quantitative Comparison — the four choices never change

You compare Quantity A and Quantity B and pick: A is greater, B is greater, they're equal, or it cannot be determined. The winning move: test edge cases — try negatives, zero, and fractions before deciding.

💡
Real example: If x² > x looks like 'A is greater', test x = 1/2: then x² < x. One counter-example flips it to 'cannot be determined'. Always try 0, 1, a negative, and a fraction.
🧠 Memory hook: QC = same four choices always. Plug in 0, 1, −1, ½ before you commit.

Numeric Entry & multi-answer — read the instruction

Numeric Entry gives no options — you type the exact number (mind units and rounding). Some multiple-choice questions ask for one or more correct answers — check whether it's 'select one' or 'select all that apply' before answering.

💡
Real example: A 'select all' question with 8 options may have 3 correct — miss one and you get zero. Read 'Indicate all such values' as a flag to check every option, not stop at the first.
🧠 Memory hook: No options = type it (watch units). 'Select all' = check every option.

Data Interpretation — one dataset, several questions

A graph or table feeds a small set of questions. Spend a moment understanding the axes, units and what's being counted before answering — the same misread (e.g. thousands vs millions) can sink every question in the set.

💡
Real example: If the y-axis is 'in millions', an answer of '5' means 5,000,000. Getting the units right once protects the whole set of questions on that chart.
🧠 Memory hook: Read the axes and units first. One misread sinks the whole set.

Frequently asked questions

What level of maths does GRE Quant test, and is a calculator provided?
Roughly high-school arithmetic, algebra, geometry and data analysis, with an on-screen calculator provided.
What are the four fixed answer choices in Quantitative Comparison?
Quantity A is greater, Quantity B is greater, the two are equal, or it cannot be determined.
What's the key technique for Quantitative Comparison?
Test edge cases — plug in 0, 1, a negative and a fraction before deciding.
What must you watch for in Numeric Entry questions?
There are no options — you type the exact number, minding units and any rounding instruction.
What should you check first on a Data Interpretation graph?
The axes, units and what's being counted — a single misread can affect every question in the set.
