Quantitative Comparison
Compare two quantities using only the stated conditions. Test an allowed fraction or a boundary value before assuming the relationship is fixed.

GRE quant practice, one skill at a time
Practise Quantitative Comparison, arithmetic, algebra and geometry with original questions and worked explanations. Start with a skill you already know, then review what slowed you down.
Choose GRE Practice for GRE formats. The shared daily challenge has the same topic rotation for every track. GRE Practice offers its own filtered topic list, including Quantitative Comparison; it does not include GMAT Data Sufficiency. QD drill timers are practice limits, not official exam pacing.
Where would you like to start?
Algebra and number properties
Review signs, integer constraints and equations before timing yourself.
Percentages and ratios
Identify the base quantity and translate the words before calculating.
Geometry and data
Use the given measurements and distinguish an exact result from an estimate.
Worked example: does squaring make a positive number larger?
Original practice example. Given x > 0, compare Quantity A: x² with Quantity B: x.
- At x = 2, Quantity A is greater: 4 > 2.
- At x = ½, Quantity B is greater: ¼ < ½.
- At x = 1, the quantities are equal.
Answer: D — the relationship cannot be determined. Both an integer and a fraction satisfy the condition, yet give different relationships. Two different permitted relationships already establish D; one example cannot establish a universal comparison.
Only test values the question allows. A few matching examples do not prove a relationship always holds; use the constraints or algebra to justify A, B or C.
A ten-minute practice slot alongside your course
- Two minutes: revisit one error from your last session and name the mistake.
- Five minutes: attempt a small timed set on that topic, within your available practice allowance.
- Three minutes: work through the explanation and write down why the tempting wrong answer fails.
This is a suggested routine, not a score-improvement claim. If the concept itself is unfamiliar, study an untimed explanation first. For a longer schedule, see the GRE study plan.
What is free, and where does Pro fit?
The shared daily challenge is free and needs no account. Extra topic practice has a daily allowance; the app shows your remaining practice before you start. Optional sign-in keeps your progress across devices. Quant Daily Pro adds unlimited topic practice. Check the current allowance and prices in the app before choosing a plan.
Quant Daily is independent supplementary practice. It does not provide a complete exam course, an official mock test, Verbal preparation or a score guarantee. Keep your course or official preparation materials for learning the syllabus, and use these drills to practise a specific skill.
