Frequently asked questions
Should I take the GMAT or the GRE?
Take the GMAT if your target schools are business schools and you are confident in data-heavy reasoning. Take the GRE if you are applying to a mix of programs, or if your verbal skills outpace your quant. Most business schools now accept both, so check each program first, then read our GMAT vs GRE decision guide.
How long does it take to prepare for the GMAT or GRE?
Most test-takers need 8 to 12 weeks at 8 to 12 hours per week to move meaningfully from their diagnostic score. If your baseline is already near your target, a focused 4-week plan can be enough. Our 8-week and 4-week study plans lay out the week-by-week schedule.
Is GMAT GRE Prep really free?
Yes. Every guide, practice question, and study plan on this site is free to read, with no account and no paywall. The site is supported in part by affiliate links on the course comparison page, which are always disclosed.
What is a good GMAT or GRE score?
A good score is one at or above the median for your target programs. On the GMAT Focus Edition scale (205 to 805), 655 and above is roughly the top decile. On the GRE, 160+ on both Verbal and Quant is competitive for selective programs. Check each school’s published class profile rather than chasing a universal number.
Do I need a paid prep course?
Not necessarily. Disciplined self-study with official practice material works well for many people, especially with a structured plan. A course helps most if you want guided sequencing, accountability, or large question banks with analytics. Our course comparison explains who each major option suits.
