GMAT GRE Prep: start here, study smart
GMAT GRE Prep is a free, independent study resource for GMAT and GRE test-takers: section guides, practice questions with worked solutions, week-by-week study plans, and honest prep-course comparisons.
How this site works
Independent of GMAC and ETS. Exam facts are checked against mba.com and ets.org, every practice question is written and solved here before it goes up, and the only revenue is disclosed affiliate links on a single page. The long version, including what this site refuses to claim about score gains, is on theeditorial standards page.
Everything publishes under one byline, Devin Marsh, which is a masthead name rather than a biography. The format and scoring figures on this page were last read back against the publishers in July 2026, and the pages they came from are listed at the foot of this one.

Practice with real worked solutions
Every question in the practice bank is original, and every solution shows the reasoning, including why the tempting wrong answers are wrong. Three to start:
Text completion: although signals a reversal

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?
The plans on this site are built around 8 to 12 weeks at 8 to 12 hours per week, which is enough time to repair weak topics and still sit several timed practice tests. 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. We have no response data from readers, so treat that range as a planning assumption rather than a measured average.
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.
