This task contains 8 examples of stationary points questions. They are scaffolded in order to increase the pace at which pupils get to practice the ideas. Some of the scaffolding might seem a bit random, but it is in places where I have found pupils struggle – factorising and solving quadratics. The trivial cases can sometimes cause more issues than the harder ones!
I have tried to group the questions so that there are similar questions next to each other. I feel that all of the Higher texts jump around too much. This task is written, very much with a mind to the fact that many pupils at Higher are insecure at pre-requisite material.
