Mock Final C, Paper 4

Before you start

• This is a closed-book exam. Calculators, notes and other aids may not be used.
• Questions 1 to 20 are short: only the final answer is marked.
• Questions 21 to 35 are five longer problems, each in three parts, set out in the steps a marker would look for; each part is marked on its answer.
• Answers must be simplified and calculator-ready: write pi/3 or sqrt(2), not a decimal approximation.
• Some answers are formulas, such as a derivative or the equation of a line. Type them in the variables the question uses.
• Every question is worth the marks shown beside it. There is no penalty for a wrong answer.
• You may move between questions freely and flag any question to come back to.
• Your answers are kept in this browser as you go, so a refresh will not lose your work. Only a submitted paper counts towards your progress.
• At 0:00 the paper is submitted as it stands.
