How much math do I need to relearn for GRE Quant?

The tested content stops before trigonometry, calculus, and formal proof. It is arithmetic, elementary algebra, plane and coordinate geometry, and descriptive statistics with basic probability. Most rebuilding time goes to exponent and root rules, percent and ratio work, and geometry formulas.

Is there a calculator on the GRE Quant section?

An on-screen calculator with basic functions and a square root key is provided. It does not accept expressions the way a graphing calculator does, and heavy reliance on it slows most test-takers down, so sessions cover which question types actually warrant it.

How long should I spend preparing for the quant section?

It depends on your starting score and target. A learner scoring in the mid-150s who needs the mid-160s typically works for several weeks on the specific error categories a diagnostic reveals, rather than reviewing all content from scratch.

Why do I keep running out of time even though I know the math?

Usually because problems are being solved fully when the question only asks for a comparison, a rough size, or one property of the answer. Sessions focus on identifying, before you start writing, whether a question wants an exact value or just enough information to choose.

GRE Quant

Graduate Tests · Test Prep

GRE Quantitative Reasoning tests arithmetic, algebra, geometry, and data analysis at roughly a high-school level, but wraps that content in question formats and time pressure that reward pattern recognition over computation. Most graduate applicants have not touched exponent rules or circle theorems in years, and the harder points are lost to Quantitative Comparison traps and misread data sets rather than to genuinely advanced math. This topic works through the content and the format together: recognising which of the four answer types you are facing, deciding when to solve algebraically versus plug in numbers or estimate, and using the on-screen calculator only where it actually saves time.

What this covers

Quantitative Comparison strategy: when 'D' is impossible, testing negatives, zero, and fractions, and simplifying both columns rather than computing them
Arithmetic and number properties under time pressure — percent change versus percentage points, ratios, remainders, factors and multiples, and exponent and root rules
Algebra: linear and quadratic equations, inequalities with sign flips, systems, functions and symbol-definition questions, and word-problem translation for rate, work, and mixture setups
Geometry and coordinate geometry: triangle relationships, circles, 3-D volume and surface area, slope and distance, and handling figures marked 'not drawn to scale'
Data Analysis: reading multi-part graph and table sets, mean versus median, standard deviation reasoning, counting, permutations, combinations, and basic probability including overlapping sets
Numeric Entry and multiple-answer questions: fraction and rounding conventions, and finding all valid values instead of stopping at the first

Where learners get stuck

Choosing 'the relationship cannot be determined' on a Quantitative Comparison where both quantities are fixed numbers: Test-takers pick D whenever the arithmetic looks messy, without noticing that if no variable appears, the comparison has one definite answer. The fix is a habit of scanning for variables before estimating.
Plugging in only positive integers when testing variables: Everyday intuition treats 'a number' as a whole positive number, so squaring seems to make things bigger and multiplying seems to increase. Negatives, zero, and values between 0 and 1 break those assumptions, and GRE writers build Quantitative Comparison answers around exactly those cases.
Reading lengths and angles off a geometry diagram that is not drawn to scale: Diagrams look reasonable, so learners assume a triangle that appears right-angled is right-angled. Only labelled values and stated facts count; unmarked geometry questions often have several valid configurations.
Reaching for the calculator on arithmetic that estimation would settle: The on-screen calculator feels like insurance, but typing costs 15-20 seconds per use. On percent and ratio questions, rounding to convenient numbers usually separates the answer choices faster than exact computation.

What a session looks like

Sessions run as spoken back-and-forth with Evelyn. You describe a problem you are stuck on, or ask for one from a chosen area, and work it aloud step by step while Evelyn probes the reasoning — why you chose to plug in numbers, what value you tested, whether you checked a negative case. Because Quantitative Comparison and data interpretation reward explanation over silent arithmetic, talking through the setup exposes shortcuts you missed. Sessions can also be used to review a practice set: report which questions you got wrong and how long each took, and work out whether the cause was content, misreading, or pacing. Written work, diagrams, and full graph sets are best kept in front of you on paper or screen while you talk.

Helpful to know first

Comfort with high-school algebra: solving linear and quadratic equations, manipulating fractions and exponents
Familiarity with basic geometry vocabulary — area, perimeter, similar triangles, the Pythagorean theorem
Access to official practice questions or a full-length practice test, so sessions can target real errors
A rough target score or programme requirement, which determines how much of the harder counting and probability material is worth drilling
