Timed practice
Full-length timed mocks, completely local in the browser.
The written fundamentals paper: multiple choice and fill-in blanks with one exact answer each, marked as the real paper marks them.
35 minutes · 14 questions · no coding · 2/5 marks
Round 1 answers are machine-checkable: multiple choice worth 2 marks, or a single exact answer worth 5. The requested form is part of the mark, as on the real paper.
Round 2 briefs rehearse the Colab sitting. Where a slice is runnable it runs in the browser against hidden checks; the rest is scored on a complete, exported pipeline rather than the cleverest model.
Every question is explained afterwards. Hints never change the score.
