Welcome! OpenMat is an open, community-built GMAT Focus Edition prep bank, and it's early — which means high-leverage first contributions are everywhere. This issue is a map of the best ways to help. No expertise required for several of them.
New here? Read CONTRIBUTING.md and CONTENT_SCHEMA.md, then pick something below. Comment to claim it so we don't double up.
✍️ Write an original question (uncovered subtopic)
The bank has gaps against the taxonomy in curriculum.md. Currently thin or missing, e.g.:
- Quant → word-problems:
mixtures, interest, translation
- Quant → number-properties:
remainders, odds-evens-signs
- Quant → counting-probability:
combinatorics
- Verbal → critical-reasoning:
paradox; reading-comprehension: dense-passages
Copy an existing file from content/questions/, follow the schema, write a full worked explanation (for someone who got it wrong) and 1–2 hints. Set status: in-review. Must be your own original work — no copied real GMAT questions.
✅ Review & verify an in-review question (no writing required)
Every question needs a second person to confirm the answer and explanation before it's verified. Pick any in-review file, solve it without peeking at the keyed answer, confirm exactly one choice is right, then open a PR bumping status: verified and adding your handle to reviewers. This is the single most unblocking thing you can do.
📚 Write a concept lesson
Any topic in curriculum.md without a lesson in content/lessons/. Follow the lesson schema: overview, core concepts, worked examples, common traps, key takeaways.
🐛 Report a bad answer or typo
Found a wrong answer or a confusing explanation? Open an issue with the question id — that's a real contribution too.
Maintainers: please add good first issue and help wanted labels and pin this issue.
