Every question is original, written fresh in the style and at the genuine difficulty of the Intermediate Challenge. What’s inside: a cover with instructions and the scoring table, 25 questions ramping from quick warm-ups to genuine Gold-level problems, a printable answer sheet with a score calculator, and a one-glance answer key. Topics span the full IMC spread: mental arithmetic, fractions and percentages, units digits and powers, divisibility, factor counting, ratio, average speed, angle chasing in polygons and isosceles triangles, circle and lens areas, a tangent-circle Pythagoras problem, counting (tilted squares, increasing digits, digit sums), probability without replacement, knights-and-knaves logic and a 1/a + 1/b Diophantine finale. The worked solutions are the real value: every question gets a step-by-step solution that explains the key insight, names the trap behind each tempting wrong option, and shows fast elimination routes, so students learn exactly when to guess and when to leave a box blank under negative marking. Ideal for Year 9 to 11 students preparing for the Intermediate Mathematical Challenge (and the Kangaroo and Olympiad follow-on rounds), for maths club practice, and for tutors and teachers setting a timed mock.
