GRE Quant Retake Strategy: Rebuild the Topics That Cost You Points

ETS organizes Quant content into arithmetic, algebra, geometry and data analysis. The level is high school mathematics and statistics, which ETS describes as generally no higher than a second course in algebra. Trigonometry, calculus and other higher mathematics are not included, the ability to construct proofs is not tested, and inferential statistics is excluded.

The current test has two Quant sections. ETS lists 12 questions in 21 minutes for the first and 15 questions in 26 minutes for the second, a little under two minutes per question either way. Like Verbal, the measure is section-level adaptive: the first section is average in difficulty and your performance on it sets the difficulty of the second.

ETS names four question formats: Quantitative Comparison, multiple choice with one answer, multiple choice with one or more answers, and Numeric Entry. Some questions stand alone and some belong to a Data Interpretation set, a group built around one shared table or graph. Numeric Entry asks you to type an integer or decimal in one box or a fraction across two boxes, and ETS tells you to enter the exact answer unless the question asks for rounding.

You get a basic on-screen calculator during Quant. ETS publishes guidelines for it, and a few details surprise people who practiced on a phone or a handheld calculator.

The biggest risk is not the tool but overusing it. ETS says most questions do not require difficult computation and suggests the calculator for genuinely tedious work such as long division, square roots and multi-digit arithmetic. Estimating before you press buttons is the simplest guard against a mis-keyed number.

Sorting your misses only by topic hides half the story. A missed probability question might reflect a gap in counting methods, a misread condition, or an arithmetic slip at the end. Each of those needs a different fix.

Go through every miss from your last attempt or a recent practice test and write two labels: the content area and topic, and the reason. Useful reasons include a concept you did not know, a formula you misremembered, a setup error in translating words to math, a careless computation or calculator entry, a figure you trusted as drawn to scale, and running out of time. If you tested recently enough, the free GRE Diagnostic Service described in the GRE Information Bulletin shows which types of questions you missed, how difficult each was and how long you spent, which speeds this step up considerably.

Concept gaps need relearning from a clean explanation, followed by easy problems before hard ones. ETS publishes a Math Review for this purpose, and working its examples by hand is time well spent. Formula slips respond to a short sheet of rules you rewrite from memory every few days until it is automatic: exponent laws, area and volume formulas, the special right triangles, percent change.

Setup errors are the most common source of lost points among strong math students. Practice by writing the equation before computing anything, labeling what each variable stands for, and checking units at the end. Careless errors shrink when you estimate the answer first and compare. ETS recommends checking whether a result is reasonable; for example, a probability must fall between 0 and 1.

Geometry questions deserve a specific note. ETS states that figures are not necessarily drawn to scale, though lines drawn straight are straight and points on a line are in the order shown. Coordinate planes, number lines and data graphs, by contrast, are drawn to scale and can be read by sight.

Here is an original problem. A jacket's price is raised 20 percent and then the new price is cut 20 percent. If the final price is 96 dollars, what was the original price?

A common error is assuming the two changes cancel, giving 96. Instead, write the original price as p. After the increase it is 1.2p; after the decrease it is 0.8 times 1.2p, or 0.96p. Setting 0.96p equal to 96 gives p equal to 100. The original price was 100 dollars. The lesson generalizes: successive percent changes multiply rather than add.

Short, frequent sessions on your weakest topics tend to beat occasional marathon sessions. RetakePrep's bank of 800 original GRE-style Verbal and Quant questions across 13 topic areas includes a review set of every question you have missed, so you can rework the problems that tripped you up as often as you need. Finish with full timed sections, including at least one official POWERPREP test, so your pacing matches the real sections.
