How are questions written and verified?

Questions are written by a generation pipeline, and every item clears solver QA before it can be served: independent solvers attempt the question, and questions with computable answers are additionally solved by a program. An item that does not clear solver QA does not reach your practice set.

This is the same pipeline that keeps the bank fresh: new questions are generated, verified, and released continuously, which is what lets PrepSavvy offer a growing bank at a one-time price.
