Chemrevise.org is run by Neil Goalby, Head of Chemistry at Bancroft’s School, an independent school in NE London. I have been teaching A-level Chemistry for 20 years and have marked A-level chemistry exams for both Edexcel and AQA. The site was first made to host my revision guides that are written for AQA A-level Chemistry. These revision guides have already been circulating on the internet for a couple of years on places like student room. This will be the place for the most up to date versions of them.
The site has now extended to cover other exam boards. (OCR and Edexcel)
The next project that is in progress is to write a more detailed e-textbook that is less syllabus specific and contains extension material and questions to answer.
