How to use these solutions

  1. Attempt the paper first, timed. The real paper allows 2 h 15 min · 90 marks. Mark what you can before looking.
  2. Compare the working, not just the answer. Method marks are where most O-Level and A-Level candidates lose their grade; each line here is a mark-bearing step.
  3. Redo the questions you got wrong a week later, without the solution open. If a topic keeps failing, that is the topic to bring to a consultation.

Need the formulas? See the O-Level maths formula sheet (what is given in the paper and what must be memorised).
