## What to reach out about - **Accuracy corrections** — if any formula, complexity class, code snippet, or explanation on a cheat sheet looks wrong, this is the single most useful kind of message we can get. Please mention the specific page and section. - **New topic requests** — if there's a subject you'd like covered as a cheat sheet, MCQ set, or flashcard deck. - **Broken links or bugs** — anything not working as expected. - **General feedback** — what's useful, what's missing, what would make this more useful for your prep. We read everything, though response times vary since this is a small, independently run project.
