Start with a random task
Open Practice and click Practice a random question. The page picks an original exam-style task so you cannot memorise a fixed order.
Filter by topic when you want only loops, arrays, strings, or procedures. Leave the filter on any topic for mixed Paper 2 revision.
Write it in the editor
Each question has a starter file. Open it in the editor, complete the algorithm, then use Run with the sample input.
Treat the sample output as a first check, then trace one edge case by hand before moving to another question.
