Many students, even the most dedicated ones, make common mistakes that cost them valuable points. In this blog, we’ll walk you through the most frequent GMAT prep mistakes, backed by data and expert tips, to help you study more effectively and achieve your target score. Let’s dive in!
12 Common GMAT Mistakes and Their Remedy
1. Skipping a Study Plan
Starting GMAT prep without a solid study plan is like heading out on a road trip without a map. According to a GMAT Club survey, 65% of students scoring below 600 admitted they didn’t have a detailed study schedule.
Tip: Make a study calendar with clear milestones. Focus on sections where you need the most improvement.
Remedy:
- Create a customized study calendar with clear daily, weekly, and monthly goals.
- Use productivity tools like Google Calendar or study planning apps.
- Reassess your plan every two weeks to adjust based on progress.
2. Ignoring Official Practice Tests
Practice makes perfect—but only if it’s the right kind. The Graduate Management Admission Council (GMAC) found that students taking 4-5 official practice tests scored about 50 points higher than those taking fewer.
Tip: Take at least five full-length practice tests under real exam conditions to build confidence.
Remedy:
- Schedule full-length practice tests every 2-3 weeks.
- Simulate real test conditions, including breaks and timing.
- Review each test thoroughly, focusing on missed questions.
3. Underestimating the Quantitative Section
Many students assume their math skills are enough and skip consistent practice. But GMAC data shows 40% of test-takers score below the 50th percentile in Quant.
Tip: Stay sharp by practicing GMAT-specific math problems regularly.
Remedy:
- Practice GMAT-specific math problems regularly.
- Focus on weak areas like algebra, geometry, and word problems.
- Use adaptive learning platforms like GMAT Club or Magoosh.
4. Relying on Memorization
The GMAT isn’t about regurgitating facts—it’s about applying concepts. Memorization alone won’t cut it, especially in Quant and Verbal sections.
Tip: Focus on understanding core concepts and practicing how to apply them in real scenarios.
Remedy:
- Focus on learning problem-solving techniques and strategies.
- Practice with challenging questions that require application.
- Engage in active learning methods like flashcards and concept maps.
5. Overlooking Data Sufficiency Questions
Data Sufficiency is unique to the GMAT and can trip up even seasoned test-takers.
Tip: Get comfortable with the question format and practice logical elimination techniques.
Remedy:
- Study the Data Sufficiency format and answer options.
- Practice regularly to improve logical reasoning skills.
- Use elimination techniques to narrow down answer choices.
6. Poor Time Management
Time flies during the GMAT! GMAC reports that 25% of students leave several questions unanswered due to running out of time.
Tip: Use a timer during practice sessions and create a pacing strategy to avoid rushing.
Remedy:
- Practice timed quizzes and full-length tests.
- Develop a pacing strategy: 2 minutes per Quant question and 1.5 minutes per Verbal question.
- Skip and return to difficult questions instead of getting stuck.
7. Skipping Analytical Writing and IR Prep
Some students think AWA and IR don’t matter much—but business schools consider all sections.
Tip: Spend time practicing essays and data interpretation questions to build a well-rounded score.
Remedy:
- Practice writing at least three AWA essays before the exam.
- Use templates for essay structuring.
- Review Integrated Reasoning questions like multi-source reasoning and two-part analysis.
8. Not Reviewing Mistakes
Learning from mistakes is key. A survey by Manhattan Prep showed that students who reviewed their errors regularly scored 70 points higher on average.
Tip: After every practice test, review wrong answers to spot and fix recurring issues.
Remedy:
- Maintain an error log with missed questions and solutions.
- Categorize errors by topic and reason (conceptual vs. careless).
- Revisit challenging topics regularly to track improvement.
9. Inconsistent Study Routine
Consistency beats cramming every time. A GMAC study found that students who studied consistently for 3-4 months scored 80 points higher on average.
Tip: Build a steady study habit—even 1-2 hours daily can make a difference.
Remedy:
- Study daily, even if it’s just for an hour.
- Establish a study routine with fixed times.
- Use study groups or accountability partners to stay motivated.
10. Neglecting the Verbal Section
Focusing only on Quant can hurt your overall score. GMAC data shows that balanced section scores lead to better results.
Tip: Give Verbal its fair share, especially Sentence Correction, Critical Reasoning, and Reading Comprehension.
Remedy:
- Practice Verbal daily, alternating between Sentence Correction, Critical Reasoning, and Reading Comprehension.
- Read challenging materials like The Economist to boost comprehension.
- Take Verbal-only practice tests to sharpen specific skills.
11. Forgetting a Guessing Strategy
Leaving questions blank is worse than guessing—unanswered questions are heavily penalized. Yet, 30% of students leave 2-3 questions unanswered.
Tip: Use an educated guessing strategy and never leave a question blank.
Remedy:
- Develop a guessing strategy for tough questions.
- Use elimination to improve your chances of guessing correctly.
- Ensure you answer every question, even if you have to guess.
12. Not Asking for Help
Some students try to do it all alone. GMAT Club data shows that students who worked with tutors scored 100 points higher on average.
Tip: If you’re stuck, consider hiring a tutor or joining a prep course.
Remedy:
- Join an online or in-person prep course.
- Hire a tutor if you struggle with specific sections.
- Engage in online forums like GMAT Club and Reddit for free peer support.
