Theme B test
One 60-minute test on all of Theme B, with the topics mixed: Section A has 15 Paper 1A questions, Section B has 2 Paper 2 questions (18 marks). One attempt; it opens with the start code your teacher gives in the room. When you submit you get your Section A score, an estimated Section B mark and an action plan in one report; the answers open when your teacher gives you the answer code.
Do the Paper 1A and Paper 2 practice of each topic first.
