Timed papers

20 questions in 75 minutes, no calculator and no formula booklet, as in the exam. The clock keeps running if you leave, the paper submits itself at 0:00, and you get a raw mark with your time on every question.

Each set is drawn from reviewed questions that never appear in topic practice, so a paper stays unseen until you sit it. Paper 2 sets are mostly logic, proof and errors in proofs, as the real paper is. Each tile names what the set has more of than the others, and its band compares its estimated difficulty (from the working each question needs) with the other sets of that paper.
