How Many Hours Do You Need to Study for the GMAT?

📚 Additional Study ResourceThis content is not part of the original "30 Day GMAT Success" book by Brandon Wu. It has been created as a supplementary resource to help GMAT students with additional practice questions, guides, and study materials.

Quick Answer

Most students need 100-200 total hours of focused GMAT study to reach their target scores. For every 10-point improvement you seek, plan approximately 10-15 hours of study. A 100-point improvement typically requires 100-150 hours over 2-3 months, studying 2-3 hours daily.

Frequently Asked Questions

Is 50 hours enough for the GMAT?

For most people, no. 50 hours might work if you're already scoring within 30-40 points of your target and have a very strong foundation. Most students need 100+ hours for meaningful improvement.

Can I study too many hours?

Yes. Beyond 250-300 hours, returns diminish significantly. If you've studied 300+ hours without reaching your target, the issue isn't hours but method. Consider changing your approach or getting professional help.

Should I track hours or progress?

Track both. Hours ensure consistency, while progress (scores, accuracy) shows effectiveness. If putting in hours without progress, adjust your method.

What if I can only study 5 hours per week?

Extend your timeline. At 5 hours/week, 150 hours takes 30 weeks (7-8 months). This is fine if you maintain consistency, but consider if you can temporarily increase availability.

Do video lessons count as study hours?

Only if you're actively engaged. Passive watching counts as 50% time. Taking notes and pausing to work problems counts as full time.
