In his books, software, and videos, Max explains the ideas using Plain English. A few well picked words explain an idea better than too many. His writing reflects the way concepts in chemistry build up, layer upon layer. He taught 13 - 20 year olds Advanced Level and GCSE chemistry, and was Head of Chemistry, and an examiner (assessor). He has taught students from all over the UK, as well as Europe, the Americas, the Middle East, Asia, and Australasia, including the USA, Canada, Nigeria, China, India, and Australia.
