I analyzed 330 public GMAT debriefs to see what high scorers had in common, then built a free tool from 15,000+ data points
Hi everyone,
I’ve been preparing for the GMAT myself. I was just deep in my own GMAT prep, falling down the r/GMAT and GMAT Club rabbit hole every night trying to figure out what actually moves the needle. One person credits a resource, another mentions a retake, someone else finally cracks DI timing — but it was all scattered across hundreds of posts and impossible to see as a whole.
So one weekend I built myself a quick dashboard just to keep track of it for my own prep. Nothing fancy, just something to stop me from re-reading the same threads over and over.
Then over time, I had about 300+ debriefs structured in one place, I started noticing real patterns — and honestly, it got more useful to me than I expected. So I cleaned it up a bit and figured other people studying right now might want to poke around in it too.
Here's examples of what falls out of the data:
You can click around the site. See where it goes. The tool is 100% free to use.
To be clear about what this is: it's just an independent side project. These are patterns in what people self-reported — not proof that any one resource or tactic causes a higher score. Treat it as a starting point for your own digging, not a verdict.

PLEASE NOTE: I SAW A LOT OF YOU USING THE MOBILE WEB, SO I'M ADJUSTING THE UX/UI TO BE MORE FRIENDLY!
Still rough around the edges — would genuinely love feedback on what's missing or what you'd want to see filtered/shown differently!
