1b. Problem Solving – Select One or More Answers
2. Quantitative Comparison
3a. Data Interpretation – Select One Answer
3b. Data Interpretation – Select One or More Answers
4a. Numeric Entry – Single Box
4b. Numeric Entry – Double Box

By understanding these question types and their answer formats, you can approach the GRE Quant section with greater clarity and confidence.


GRE Problem Solving Practice Questions

Problem solving questions are the most common and familiar type of GRE Math question. These questions—often word problems—assess your ability to apply mathematical concepts and real-world quantitative reasoning to solve a variety of problems. There are two main types of problem solving questions you’ll encounter on the GRE, and understanding the difference between them is key to approaching each one effectively.

Two Types of Problem Solving Questions

  1. Multiple Choice — Select One Answer: In this question type, you will be asked to select only one correct answer from a list of five possible options. The goal is to carefully evaluate the information provided and determine which of the five answer choices is correct. This format is straightforward, but some questions may contain distractor answers that can mislead you if you aren’t careful.
  2. Multiple Choice — Select One or More Answers: This variation asks you to select one or more correct answers from a list of options. Unlike the first type, the number of answers you should select is not always specified.

It is crucial to read the question carefully to determine how many answers are required. Sometimes, you might need to select just one answer, while other times, you’ll need to select two or more. Failing to select the correct number of answers can result in lost points, so pay close attention to the instructions.

Tackling Problem Solving Questions

No matter the specific format, the key to solving problem solving questions is understanding the problem, identifying the most efficient approach, and recognizing patterns. While a strong foundation in mathematics is essential, it’s just as important to use strategies that streamline the problem solving process. Here are some strategies to help you succeed:

  1. Read the Question Carefully: Always read the problem carefully to ensure you understand exactly what is being asked. Make sure to identify whether the question requires you to select just one answer or multiple answers. Misreading this can lead to mistakes, especially in the “select one or more” format.
  2. Examine the Answer Choices: In multiple choice — select one answer questions, you can often save time by evaluating the answer choices before working through the problem. This technique, called backsolving, involves plugging the answer choices into the problem to see which one satisfies the given conditions. In the select one or more answers format, this strategy can also be useful, but remember you may need to test multiple choices at once to find all the correct answers.
  3. Consider All Information Given: Some problem solving questions include extra details designed to distract you. Focus on the relevant information and avoid overcomplicating the problem by getting bogged down in unnecessary data.
  4. Identify and Leverage Mathematical Patterns: Many GRE problems contain numerical or algebraic patterns that you can recognize and use to solve the problem faster. Identifying these patterns can help you solve the problem more efficiently, saving you time and reducing the likelihood of errors.
  5. Choose the Best Method for the Situation: Each question may require a different approach, depending on the problem’s structure—some questions might require backsolving, number picking, or logical reasoning, where others might require direct algebraic manipulation or knowledge of quadratic equations. The key is to select the strategy that works best for the specific problem at hand.

To illustrate how to tackle these questions, we’ve broken down two official GRE Problem Solving questions, demonstrating practical strategies for success.

GRE Quantitative Comparison Practice Questions

Quantitative comparison questions are a unique subset of GRE multiple-choice questions, differing significantly from standard problem solving ones. While problem solving questions always offer five answer choices, quantitative comparison questions have only four, which remain consistent across all questions and are presented in the same order:

  1. Quantity A is greater.
  2. Quantity B is greater.
  3. The two quantities are equal.
  4. The relationship cannot be determined from the information given.

Each question provides two quantities—Quantity A and Quantity B—and asks you to determine the relationship between them. While the format may seem straightforward, these questions are designed to mislead, and many test-takers fall into traps, overlooking the correct answer.

Tackling Quantitative Comparison Questions

The biggest mistake students make is approaching these GRE math questions without a clear, effective strategy to evaluate the relationship between the quantities. Without reliable methods, it’s easy to get tripped up by the trickier problems.

Fortunately, there are proven techniques and strategies to help you improve accuracy and confidence in solving these questions. Menlo Coaching GRE tutoring focuses on teaching these principles, equipping students with the tools needed to master even the most complex quantitative comparison problems.

To demonstrate how to approach these questions, we’ve broken down two official GRE quantitative comparison sample questions, showcasing practical strategies for success.

`(x+5)^2 – (y-3)^2 = 0`
`x+y=2`

Quantity A: `x-y`

Quantity B: 0

A. Quantity A is greater.
B. Quantity B is greater.
C. The two quantities are equal.
D. The relationship cannot be determined from the information given.

See Answer and Explanation

`x!=1`

Quantity A: `(x^2-2)/(x-1)`

Quantity B: `x-2`

A. Quantity A is greater.
B. Quantity B is greater.
C. The two quantities are equal.
D. The relationship cannot be determined from the information given.

GRE Data Interpretation Practice Questions

Data interpretation questions require you to analyze and interpret data presented in various formats, such as tables, graphs, or charts. These questions test your data analysis and ability to extract meaningful insights and make accurate assessments based on the given visuals.

Two Types of Data Interpretation Questions

Each set typically includes three related questions, giving you the chance to explore the data more deeply.

Tackling Data Interpretation Questions

To succeed in data interpretation questions, practice analyzing different data types like pie charts, bar graphs, and scatter plots. Develop efficient strategies for extracting information and responding within time limits. In particular, working with timed practice sets can help improve your efficiency in data interpretation questions.

  1. Quickly Scan the Data: Start by briefly scanning the visuals to get a sense of what’s being measured. Focus on the title, axis labels, and scale markings, as these provide context.
  2. Use the Data Provided: Stick to the information shown in the graphs or tables. Do not rely on external knowledge; the questions are designed to be answered using only the provided data.
  3. Estimate or Read Values from the Scales: For quick interpretations, identify scale markings and estimate values when exact numbers aren’t necessary. This helps save time while maintaining accuracy.

With regular practice, you can improve your ability to quickly interpret data and answer questions accurately, boosting your GRE score.

GRE Numeric Entry Practice Questions

Numeric entry questions ask you to manually enter your answer, whether as an integer, decimal, or fraction. These questions evaluate your ability to perform mathematical calculations and provide accurate solutions.

Types of Numeric Entry Questions:

These questions test a range of concepts, including arithmetic, algebra, geometry, and statistics. Be mindful of the answer formatting, as mistakes in entering decimals, fractions, or scientific notation can lead to incorrect answers.

Tackling Numeric Entry Questions

  1. Understand the Question: Make sure you know exactly what the problem is asking before you start solving. Sometimes, students perform the necessary calculations but miss a small detail that renders their answer incorrect.
  2. Pay Attention to Rounding: If rounding is required, follow the instructions precisely. Round your answer to the specified degree, whether it’s to the nearest whole number or decimal place.
  3. Perform a Quick Check: After entering your answer, take a moment to ensure it makes sense. For example, if the problem asks for an average, verify that the result aligns with the data provided.

With careful attention to detail and formatting, you can improve your accuracy and efficiency in numeric entry questions, helping you achieve a higher score.


How to Practice for the Quantitative Section of the GRE

Effective preparation for the Quantitative section of the GRE requires more than just memorizing formulas and solving practice problems. It’s about developing a personalized strategy that aligns with your strengths, weaknesses, and goals. By using a combination of official practice questions, timed practice sets, and full-length practice tests, you can significantly improve your performance and tackle the GRE with confidence.

Start with Official Practice Questions

One of the best ways to prepare for the GRE Quantitative section is by working with official practice questions provided by ETS, the creators of the GRE. These questions mirror the format and difficulty of the actual test, offering an authentic representation of what you’ll encounter on exam day.

Begin by working through individual problem solving and quantitative comparison questions. Focus on understanding the underlying concepts and strategies for each type of question. Pay attention to patterns in the questions, such as common problem types or repeated question formats. These insights will help you recognize the most efficient strategies during the real test.

For data interpretation and numeric entry questions, practice interpreting graphs, tables, and charts and entering answers manually. Working with official practice questions will familiarize you with the exact way these questions are formatted and the precision required for answers.

Use Timed Practice Sets

Once you’ve gone through individual practice questions, the next step is to incorporate timed practice sets into your study routine. Timed sets simulate the actual testing environment and help you build the pacing and mental stamina needed to complete the Quantitative section within the allotted time.

Try working with sets that consist of 10-15 questions from a variety of topics, aiming to complete them within the same time limits as the actual test. Pay attention to the clock, but don’t rush. Focus on the quality of your answers while managing your time effectively. This exercise will help you gauge how much time you should spend on each question and identify any areas where you need to improve your speed or accuracy.

Take Full-Length Practice Tests

Full-length practice tests are essential for replicating the experience of taking the entire GRE. These tests typically include both the Quantitative and Verbal sections, allowing you to practice maintaining focus and stamina throughout the full 3-hour exam. Taking these tests is vital for understanding how your performance in one section can affect the other, especially when you have to manage your energy and attention over an extended period.

After each practice test, thoroughly review your answers, especially those you got wrong. Understanding why you made a mistake and how to correct it will help prevent similar errors in the future. As you take more practice tests, you’ll notice improvements in your overall performance and learn how to refine your test-taking strategies—but remember that only a limited number of official practice tests are available, and you should strategically incorporate the official GRE practice tests available to you over the course of your GRE prep.

Leverage the Official Exams

In addition to official practice questions, utilizing the official GRE exam once you’ve reached a level of readiness is a great way to gauge your preparation. If you’re feeling confident in your strategy and timing, consider scheduling a real GRE exam at your testing center. This will give you valuable experience with the actual test format and provide you with an official score to track your progress.

Develop a Personalized Strategy

While practice is key to success, having a personalized strategy is equally important. This strategy should be based on your strengths, weaknesses, and specific goals. For example, if you struggle with data interpretation questions, you might dedicate more time to analyzing graphs and tables. Or, if you’re stronger in arithmetic but weaker in algebra, allocate more time to working on algebraic concepts.

Our GRE tutoring team can help you create a customized strategy, ensuring you spend time focusing on areas that will make the most significant impact on your score. With targeted practice and a clear plan, you’ll be able to approach the Quantitative section of the GRE with confidence and maximize your score.
