Maths a level c1

Core Mathematics 1

C1 was first introduced in 2004 as part of the Core series which replaced the old Pure system. It was created to help build a bridge between GCSE maths and A level maths, expanding mainly on what is dealt with at Higher Level GCSE. The topics that are new include differentiation and integration, both of which are covered on a very simple level. C1 aims to teach you the basics of this topics, so that when you move onto the later units (C2,C3,C4) you will have a basic understanding. Note that C1 is a non-calculator paper, as it is partly aimed to build and develop your mental maths skills.
