GRE Quantitative Reasoning Strategy

Quantitative Reasoning comprises two of the five sections of the GRE, along with one Analytical Writing section and two Verbal Reasoning sections. Test-takers receive section-level scores for Quantitative Reasoning and Verbal Reasoning, as well as a total GRE score made up of all four sections (the Analytical Writing section is scored separately). For many test-takers, Quantitative Reasoning questions are the most stressful part of the GRE, and while they are admittedly challenging, they can also be mastered through focused and consistent practice.

Students who are studying for the GRE should prepare for the Quantitative Reasoning sections by reviewing the mathematical concepts that will be covered and by completing both practice problems and full practice tests. There are a total of 27 Quantitative Reasoning questions on the GRE, 12 questions in the first section and 15 questions in the second section. Test-takers are given less than two minutes per question, which means you need to know the most effective strategies for answering these questions in the most efficient manner possible.

One of the best ways of mastering time-saving techniques is to practice them with a test prep instructor or tutor. At Manhattan Review, our tutors work with students to identify weaknesses quickly so that study time can be spent strengthening the skills that will lead to a top score. We have shared effective problem-solving strategies below, as well as techniques suggested by Educational Testing Service (ETS), the creator and administer of the GRE. Once you understand the skills you need to develop and begin the process of mastering them, it is important to practice frequently and regularly to become an expert at utilizing the techniques that will be most beneficial to you on test day.

Quantitative Problem-Solving Approach

Quantitative Reasoning sections cover four content areas:

  1. Arithmetic
  2. Algebra
  3. Geometry
  4. Data Analysis

The topics covered are generally taught in high school algebra courses or introductory statistics courses. For students who obtained an undergraduate degree in mathematics or science, much of the content in the Quantitative Reasoning sections will likely be familiar. For students with stronger backgrounds in the arts, humanities, or social sciences, these topics may be less familiar and require additional practice in order to become familiar with and comfortable using quantitative reasoning strategies.

First, it is important to read the problem carefully and ensure that you understand the information and what you are required to solve. Information may be given in words, mathematical expressions, or a combination of both. Quantitative information may come in the form of data presentations, coordinate systems, geometric figures, formulas, conditions, or definitions. In addition to understanding the problem, finding the correct answer requires understanding what needs to be accomplished in order to solve the problem.

Solving a problem requires strategically choosing and using mathematical facts and information. What works for solving one problem may not be effective for solving another, although many problems can be solved using more than one strategy. Think of problem-solving strategies as tools in your toolbox; you need to know the tools you have as well as how to best use those tools to accomplish specific tasks.

Once you arrive at a solution, be sure to check your answer to ensure that it is reasonable and correct. Evaluate whether you have answered the appropriate question, check that the strategy you used was correct (and maybe use an alternate strategy to check your work, if convenient), and double-check that you did not make any computational errors.

ETS Problem-Solving Strategies

ETS lists fourteen strategies to help solve Quantitative Reasoning problems:

  1. Translate from words to an arithmetic or algebraic representation;
  2. Translate from words to a figure or diagram;
  3. Translate from an algebraic to a graphical representation;
  4. Translate from a figure to an arithmetic or algebraic representation;
  5. Simplify an arithmetic or algebraic representation;
  6. Add information to a geometric figure;
  7. Find a pattern;
  8. Search for a mathematical relationship;
  9. Estimate;
  10. Trial and error;
  11. Divide into cases;
  12. Adapt solutions to related problems;
  13. Determine whether a conclusion follows from the information given;
  14. Determine what additional information is sufficient to solve a problem.

Details for each of these strategies can be found on the ETS website.

Additional strategies that may prove helpful include:

  • Familiarize yourself with Quantitative Reasoning question types (Quantitative Comparison, Problem-Solving Multiple-Choice (one answer); Problem-Solving Multiple-Choice (more than one answer), and Data Interpretation.
  • Practice estimation and mental math.
  • Use the “Mark and Review” feature so you don’t get stuck on one problem.
  • Answer every question and don’t be afraid to take your best guess, as there are no penalties for incorrect answers.
  • Practice taking the GRE under timed conditions to learn important time management skills.
  • Review your mistakes to understand what areas of test prep require additional study.
  • Use real numbers in calculations if the abstract nature of the problem is too confusing.

Manhattan Review offers a suite of preparation materials to help students studying for the GRE Quantitative Reasoning sections.
