How do I study for the GMAT quants in the last month?

Question

V Gupta · Accepted Answer

In the last month, forget about learning everything&mdash;just focus on what shows up the most. That means number properties, arithmetic (especially ratios, percentages, and word problems), algebra, and basic geometry.
Spend the first 10&ndash;12 days reviewing these topics by doing timed topic-wise drills. 15&ndash;20 questions per day is enough if you track why each one went wrong: was it a silly mistake, concept error, or time pressure?
Then move into mixed sets&mdash;this is where most people slip. Do 31-question timed Quant sections every 3 days. Review them hard, especially your time splits. If a question takes over 2.5 minutes, flag it&mdash;it might not be worth solving fully under test conditions.
Don&rsquo;t overdo mocks. Two full mocks in the final 10 days are enough. Focus more on question review than your total score. You&rsquo;re better off mastering medium questions than chasing the toughest ones.

Last month prep is all about decision-making under pressure&mdash;not just formulas. A lot of students know the concepts but freeze when questions get twisted or wordy. That&rsquo;s what kills the score.
Here&rsquo;s what helps:

Stick to core GMAT topics. Make a list of 5&ndash;6 weak areas and revise only those. Don&rsquo;t waste time on fringe stuff like 3D geometry or heavy stats.
Do timed drills of 10&ndash;15 questions every day. Use a timer and review not just mistakes, but why your method was inefficient.
Keep an error log with categories like &ldquo;rushed,&rdquo; &ldquo;misread,&rdquo; or &ldquo;concept gap.&rdquo; Review that more than you review theory notes.
Mix in official GMAT questions every few days. They&rsquo;re closest to what you&rsquo;ll face on test day.

If you&rsquo;ve done some prep already, one month is enough to hit Q45+&mdash;but only if your revision is tight and goal-driven.

The last month is really about sharpening your Quant performance, not learning new material. Start by prioritizing official GMAT Focus questions,  they match the real exam&rsquo;s logic better than anything else.
Go back to questions you&rsquo;ve already solved. Review both correct and incorrect ones. Focus on how fast you're recognizing question types. If you're spending over 2 minutes, it's usually a sign you missed a shortcut or didn&rsquo;t spot the pattern early.
Make a list of your weak areas, not full topics, but sub-areas. For example, not just &ldquo;algebra&rdquo; but &ldquo;absolute value inequalities&rdquo; or &ldquo;work rate word problems.&rdquo; Target practice on these smaller pockets. Keep a one-page formula sheet. Review it daily so you're not second-guessing formulas during the test.
Finally, take full-length mocks every few days under strict timing. The goal is to normalize test pressure and build mental endurance.

When you&rsquo;ve got just one month to prep for GMAT Quant, you need to study smart, not wide.

Start with a quick diagnostic using an official mock. That shows exactly which areas to target.
Build your daily study around 2-hour focused blocks: one hour on targeted weak topics, one hour of mixed timed practice.
Don&rsquo;t try to cover every Quant topic. Focus on high-yield areas: arithmetic, number properties, word problems, inequalities, and Data Sufficiency logic.
Use official GMAT Focus questions as your main resource. They train you in the actual question style and traps.
Every night, review your mistakes in detail. Write down why you missed each one and review that log every few days.
Add 10 minutes daily of mental math drills. This helps you avoid wasting time on basic calculations during the real test.
