One important mathematical technique that can be really useful in solving STEP and other advanced mathematics examinations questions is being able to spot a clever substitution. The right substitution can make an equation or integral that seems intractable at first glance into something straightforward to solve. This collection of problems and articles showcase the technique of the clever substitution.
