Numerical reasoning practice by topic

Real test questions rarely use one skill in isolation — a single SHL or CCAT item might fold a table read, a percentage change and a ratio into one go. But every question decomposes into the twelve areas below, and the fastest way to raise your score is to find the two or three actually costing you marks and drill them until they’re automatic.

Short on time? Start with the highest-leverage areas: percentages (especially percentage change and reverse percentages), ratios & proportion, and reading data from tables and charts — together they cover most questions on graduate and managerial tests. Rates, averages and currency conversion come up often enough to be worth a pass too. Each topic page gives you the method, worked examples, and a drill of real test-format questions with the named mistake behind every wrong option. Work one area at a time, check the worked solution on anything you miss, then retake the free test to watch your weak spots move.
