Frequently Asked Questions
The GMAT Quantitative section tests your ability to reason mathematically and solve problems using data analysis, geometry, algebra, and arithmetic. You'll encounter two question types: Data Sufficiency (which asks whether you have enough information to answer a question) and Problem Solving (traditional multiple-choice math problems). The section lasts 62 minutes and includes 31 questions, so pacing and strategic thinking are just as important as computational skills.
Score improvement depends on your starting point and study commitment, but most students see meaningful gains with focused, personalized instruction. Many students improve by 5-10 percentile points or more when they identify specific weak areas—like struggling with geometry or Data Sufficiency logic—and work systematically to strengthen them. A tutor can help you pinpoint exactly where you're losing points and create a targeted study plan rather than spending time on concepts you already know.
Timing is one of the biggest challenges on GMAT Quantitative—you have roughly 2 minutes per question. The key is learning which questions to tackle first, when to make an educated guess and move on, and how to recognize question types quickly. A tutor can teach you strategic pacing techniques, help you practice under timed conditions, and show you how to avoid common time-wasters like overthinking or getting stuck on one problem.
Data Sufficiency is unique to the GMAT and trips up many test-takers because it's not about solving the problem—it's about determining whether you have enough information to solve it. This requires a different mindset than traditional math problems. Many students struggle with the logic of combining statements or recognizing when information is redundant. Personalized tutoring helps you master the specific reasoning patterns and decision trees that make these questions manageable.
Practice tests are essential—they show you how you perform under real time pressure and help identify patterns in your mistakes. Taking full-length practice tests early reveals whether your struggles are with specific topics (like probability or coordinate geometry) or with pacing and test anxiety. A tutor can review your practice test results to create a focused study plan and help you understand why you missed questions, not just what the right answer is.
Start by analyzing your practice test results to spot patterns—are you missing geometry questions, making careless errors under time pressure, or struggling with specific algebra concepts? Varsity Tutors connects you with tutors who can diagnose exactly where you're losing points and create a personalized study plan to address those gaps. Rather than reviewing everything, targeted instruction on your specific weak areas is the fastest path to score improvement.
Most students benefit from 4-12 weeks of focused preparation, depending on their starting level and target score. If you're already strong in math, you might need less time; if you're rusty with algebra or geometry, longer preparation helps. A tutor can assess your current skills and create a realistic timeline based on your specific goals, ensuring you're not cramming or wasting time on unnecessary review.
Test anxiety often comes from feeling unprepared or uncertain about how to approach unfamiliar question types. When you work with a tutor, you build confidence through repeated practice with real GMAT questions, learn strategies that reduce decision-making stress, and get comfortable with the test format before test day. Having a clear game plan and knowing you've practiced thoroughly is one of the best remedies for anxiety.
