Is 30 Days Enough 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

Yes, 30 days can be enough to prepare for the GMAT, but success depends on three critical factors: your starting score (ideally 600+), available study time (6-8 hours daily), and realistic goals (50-100 point improvement). I personally scored 780 in 30 days, and thousands of students have succeeded with intensive one-month preparation.

Frequently Asked Questions

What if I'm not improving after 2 weeks?

Extend to 45-60 days immediately. The 30-day timeline isn't worth risking a low score. Better to adjust early than push through unsuccessfully.

Should I quit my job for 30-day prep?

Generally no, unless you're between jobs already. Consider taking vacation time or unpaid leave instead. The stress of unemployment can negatively impact performance.

Can I really improve 100+ points in 30 days?

Possible but rare (top 10% of students). Most achieve 50-100 point improvements. Set realistic expectations: 70-point improvement is excellent for 30 days.

What if I can only study 4 hours daily?

Extend to 45-60 days. The 30-day plan requires 6-8 hours minimum. Quality matters, but there's a minimum quantity threshold for success.

Is online or in-person prep better for 30 days?

Self-study with quality materials is most efficient for 30 days. Courses often move too slowly for intensive timelines. Consider private tutoring for specific weaknesses only.

  • Your diagnostic is within 100 points of target
  • You can dedicate 6+ hours daily
