How we check every question
Our checks are automated, and we say so plainly: there is no human review panel behind them. Report an error.
- Every question is written from scratch. None is copied from official papers or from other publishers.
- Every answer key is verified by code at build time: each answer is recomputed independently, and a paper cannot be built if any answer disagrees with its key.
- Each question has exactly one correct option, and the correct letter is spread evenly across the options.
- If you find a mistake, report it on the error page. We check it, correct the paper quickly and send the corrected files free to everyone who bought it.
