CSSE-style Mathematics Mock 5 - Essex 11+. SECTION A: MATHEMATICS (60 minutes - this is the only section in the paper). Write your answers, with full working, in the space provided; method marks (M1) are awarded for correct working even where the final answer is wrong. Calculators are NOT allowed. You have 60 minutes to attempt all 30 questions, worth 89 marks in total. This is a different set of questions from Mock 1 (EP.T4), Mock 2 (EP.T15), Mock 3 (EP.T19) and Mock 4 (EP.T29). The questions get harder as the paper goes on - the final five are genuine problem-solving puzzles designed to stretch even strong candidates, so keep an eye on the clock and do not spend too long on any one question.
