I picked up a 1978 CSE textbook in Oxfam. CSE Mathematics 1 The Core Course by A Greer I thought people might be interested in some of the questions. Factorise (a) 4x^2-9y^2 (b) 21x^2+37x+10 Find the values of (a) 27^(1/3) (b) 5^2 x 5 ^ (1/2) x 5 ^ (3/2) (c) 3^-4 Simplify 1/x + 1/3x If the logarithm of 5.444 is 0.7359 the logarithm of 544400 is (multiple choice). The curved surface of a cone has an area of 20.5cm^2. What is the curved surface area of a similar cone whose height is 1.5 times as great as the first cone? I'll just list a few more topics that may be surprising. Trigonometry Sets Solving simultaneous equations by inverting a 2x2 matrix Transformations including glide reflections. This isn't foundation GCSE or even intermediate. Surely this is higher GCSE material these days.
