Past-paper exam practice

Time-locked exam simulation — no AI hints during the run. The timer cannot be extended once started. Each answer is cryptographically chained so the marker can verify the paper hasn't been tampered with. Grading returns a predictedgrade in your jurisdiction's units (GCSE 9–1, A-Level A*–E, AP 1–5, IB 1–7, NCEA Achieved/Merit/Excellence, VCE study score, NSC %, JEE Main, NEET).
