The GMAT Quantitative section is designed to test your problem-solving skills and ability to reason with numbers, all while under the pressure of the ticking clock. The challenge lies not in complex calculations but in understanding what’s being asked for and applying the correct level of abstraction to navigate to the correct answer quickly and confidently. In this guide, we’ll cover 8 key tips to help you conquer the Quant section of the GMAT.

The GMAT Quantitative Section Basics

The GMAT Quantitative section in the GMAT consists solely of Problem Solving questions — Data Sufficiency has moved to the Data Insights section, while geometry has been phased out with the advent of the GMAT focus in 2023.
These Problem Solving questions assess your ability to apply logic and quantitative reasoning to solve problems, using basic arithmetic, algebra, statistics and number properties. Importantly, calculators are not permitted, reinforcing the need to master mental math, estimation techniques, and a problem driven approach.
The GMAT Quant section differentiates candidates based on their higher level thinking skills. This means that the quant problems are not a race to see who can “math” the fastest. Rather, it’s your ability to see around the problem, to crack it open like a riddle, that will elevate you from your peers. You’ll need to know the math, but as a point of leverage, not as a test of your computational skills.

9 GMAT Quant Tips

Let’s dive into nine essential strategies that will help you master the GMAT Quant section.

1. Understand the Evolving GMAT Test Format

The GMAT Focus Edition has introduced changes, particularly in the Quant section, with the elimination of geometry questions and the integration of the Data Insights section. Stay updated on the test format and adapt your preparation accordingly. Familiarizing yourself with the latest version of the exam ensures that you’re well-prepared for the types of questions you’ll face.

Pro Tip: Don’t rely on old study materials—make sure you’re practicing with resources that reflect the current GMAT format.

2. If You’re Doing Math…

Many test-takers fall into the trap of over-processing questions. If you find yourself doing long calculations or plugging in numbers, stop and reassess. GMAT problems are often designed to mislead you into taking the most obvious (and time-consuming) path. Instead, look for shortcuts or alternative methods that bypass heavy calculations.

As Mike Diamond, Director of Curriculum Development at Apex, advises: “If you’re doing math, you’re doing something wrong.” This approach encourages you to find efficient, logical solutions rather than getting bogged down in complex arithmetic.

3. Use Alternative Solution Paths

Don’t rely on default-solving mechanisms (DSMs). While traditional problem-solving methods might feel familiar, they’re often not the most efficient for the GMAT. Train yourself to think beyond the obvious approach and consider alternative methods that save time. For example, if a problem seems to require lengthy algebra, check if estimation or logical reasoning can get you to the answer more quickly.

4. Master the Interpretive Layer

GMAT Quant questions are full of details, but not all are relevant to solving the problem. Read carefully, but don’t process every piece of information right away. Focus on identifying the key pieces of data that will guide your solution. Start by understanding what’s being asked before diving into details. This way, you avoid wasting time on unnecessary writing or useless calculations.

5. Simplify the Answers

Often, the solution to a GMAT Quant problem is more about estimation and understanding scale or divisibility. For instance, if answer choices are spread widely apart, use this to your advantage. Estimate the answer rather than calculating it to the decimal point. You can save tons of time by recognizing when an approximation or particular characteristic is enough to address what’s being asked. 

6. Diversify Your GMAT Prep

While official GMAT materials are essential, integrating additional resources like the Apex platform can elevate your preparation. The Apex platform reflects the real test-taking experience, providing GMAT-style questions that mirror the difficulty, structure, and complexity of the actual exam.

A key advantage of the Apex platform is that it encourages you to think like the latest GMAT test writers, helping you break down and anticipate question structures. This improves your problem-solving skills and also enables you to design your own GMAT problems, deepening your understanding of the test’s logic and making you more adaptable to different problem types.

Make sure your study materials reflect the GMAT’s complexity. Poorly constructed problems (from many notable guides) can promote habits that don’t align with the test’s design, potentially harming your overall performance. Apex’s platform ensures that each problem aligns with GMAT logic, so you’re practicing with purpose.

7. Less is More – Make the Least of Your Scrap Paper

Many test-takers overuse their scrap paper or whiteboard. Writing everything down can slow you down and shift your focus from thinking critically to processing mechanically. Use your scrap paper sparingly; write only what’s necessary when you reach data overload. Focus on keeping your attention on solving the problem mentally whenever possible. This approach keeps you efficient and sharp. You’ll be surprised how often not being able to do calculations redirects you to a more efficient solution path.

8. Aim for 45 seconds, not 2 minutes

Effective time management is key to mastering the GMAT Quant section. First, the methodology. Within the first 30 seconds of encountering a problem, you should be able to identify the problem type, what’s being asked, and the most likely solution path. The rest is execution. 

On to the bigger picture. You should aim to spend about 45 seconds to one minute on most problems. If you’re getting it right, but it’s taking 2 minutes or longer, there’s still a massive opportunity to up your game by finding a more efficient solution path. This will free up your time for creative problem-solving on the edge problems discussed above.

9. Play at your level – don’t shoot the moon

A common error is to try to find the most challenging quant questions around. Instead, you’ll be better served first mastering stronger, alternative solution paths on problems you already understand.

After that, work on “edge” problems – those that are just out of reach. Because the test is adaptive, it’s vital to prepare for the problems you’re most likely to see. The most challenging problems are appropriate, but only once you’ve mastered the easier stuff. Many candidates will never need to do a top 1% problem to get a 645+ or even 700+ GMAT score, so take things easy, one step at a time.
