About me - I am an experienced teacher of A-level chemistry, having taught AQA for 7 years and Edexcel for 2 years - and have been slightly frustrated at the lack of Edexcel-specific resources in that time. I have a particular interest in helping students develop their mathematical skills, and have gained an understanding of where they typically struggle in the transition from GCSE.
