How do you get good at GMAT Quant if you haven't done math in years?

Getting good at GMAT Quant after years away from math isn’t about memorizing tricks. It’s about rebuilding how you think about problems.

• Start with absolute basics. Spend the first 2-3 weeks only on arithmetic: adding, subtracting, percentages, fractions, and ratios.
• Use simple drills daily. For example, practice converting fractions to decimals quickly, or calculating percentage increases in your head.
• When you start official questions, avoid timed practice at first. Focus on fully understanding how each question works.
• Build a small notebook where you write down each new formula or rule you come across. Keep reviewing it every few days.
• If the basics feel overwhelming, you can also use Mentr Me. They have structured resources to help build GMAT Quant fundamentals from scratch.
• As you get more comfortable, introduce Data Sufficiency early. It forces you to focus on logic, not just calculations.
• Finally, schedule frequent short sessions instead of long study blocks. Math retention builds better with daily consistency.

When it’s been years since you last touched math, trying to jump straight into GMAT Quant can feel overwhelming. The first step isn’t to rush into official questions but to rebuild your foundation slowly.

Focus on arithmetic, fractions, percentages, ratios, and basic algebra first. These are everywhere on GMAT Quant, and getting fully comfortable with them makes advanced topics way easier. Use beginner-friendly resources like Khan Academy or the early modules of TTP just to relearn how numbers behave.

Once basics feel solid, start building a "question type tracker." Every time you solve a new problem, label it: word problem? number properties? inequalities? Over time, this helps you recognize patterns faster, which is what GMAT really tests.

And don’t try to master everything at once. The early goal is accuracy. Speed comes later once you trust your process.

 If you haven’t done math in years, it’s okay — many have started from the same point and built strong GMAT Quant scores. Begin by revisiting the basics with a solid book like the Manhattan Prep guides or online platforms like Magoosh. Aim for 15–20 questions every day, focusing first on understanding why you got questions wrong.

What’s overlooked is how much you can gain from “passive review” — spend a few minutes each day reading worked examples, even when you’re tired. This builds an instinct for spotting patterns quickly. It also helps to practice estimating quickly, because the test doesn’t always reward long calculations. Another powerful approach is making an error journal, noting why a mistake happened, not just that it happened.

With this approach, 2–3 months of consistent effort can turn rusty math skills into a strong, confident GMAT Quant performance.
