Doc Brown's Travel Pictures

Above are links to the main sections of Doc Brown's Chemistry's website, these in turn link to other sub-indexes from which I hope you will bookmark useful and relevant links for your science course. At the top and bottom of all revision notes pages of Doc Brown's Chemistry are more detailed sets of navigation bar buttons to which you should make yourself familiar. The Google search engine is dedicated to Doc Brown's Chemistry's website putting in 'anything of interest' and you can put in multiple words to get the best page match from Doc Brown's website.

"Doc Brown's Chemistry" is a website designed for UK science students studying GCSE Biology, GCSE/IGCSE Chemistry, GCSE Physics and Advanced Level Chemistry. My website covers the current science syllabus specifications from AQA, Edexcel and OCR examination boards. This science revision e-learning  website includes notes & quizzes for chemistry, but includes some biology and physics too AND lots of 'unofficial' revision summaries for ALL the current GCSE Sciences (links below). The new GCSE specifications starting in September 2016 will be eventually covered completely by Doc Brown's Chemistry plus biology and physics revision notes and specification summaries.

CV and 1993 still with beardCV and 2006 still click click!!I hope these web pages of 'Doc Brown's Chemistry'  help your studies! and a warm welcome to the HOMEPAGE of doc b's "Chemistry Online" revision website. This was my millennium 'teaching & learning' project and Doc Brown (teacher) has been online since 2000! Its a big SCIENCE WEBSITE to get to know from a retired CHEMISTRY teacher (and some physics and general science for teaching and learning purposes), SO, use the appropriate INDEXES and Google custom 'Doc Brown's Site' SEARCH too! 'Doc Brown's Chemistry' (all material © Dr Phil Brown 2000-2016) has lots of  science revision notes & quizzes, mainly an e-learning website for chemistry, but includes some biology and physics too AND lots of 'unofficial' revision summaries for ALL the current English GCSE Science courses

IN FUTURE THIS WILL BE MY MAIN GCSE SCIENCE EXAM REVISION SUMMARY INDEX for biology, chemistry, physics and science GCSE courses - The 'old' navigation system for GCSE science courses catered for on Doc Brown's Chemistry was far too complicated (big apology in retrospect). Things will be a lot simpler from July 2017 onwards when the 'old' GCSE courses have finished and the 'old' GCSE science summary pages dealt with by deletion or conversion to stand alone notes!
