"The questions in the six levels of this of exercises range from the laughingly easy to the headscratchingly hard. The last question of level 6 was adapted from one that appeared on a Senior Mathematical Challenge (JMC) paper.
The SMC is a 90minute, multiplechoice competition from the UK Mathematics Trust aimed at students (Year 13 and below) across the UK. It encourages mathematical reasoning, precision of thought, and fluency in using basic mathematical techniques to solve interesting problems. The problems on the Senior Mathematical Challenge are designed to make students think. Most are accessible, yet still challenge those with more experience."
