Doc Brown's Revision notes & quizzes for revising Science-CHEMISTRY online from the year 2000

ALL of this PRE-UNIVERSITY internet website CONTENT Dr Phil Brown 1999-2014

Year 13 A2 Advanced Level Salters Chemistry Students at Whitby Community College Year 13 January 2002

As far as I know, my website runs on all browsers, pc, laptop, notepad, netbooks, ipads, epad tablet, android and even the iphone - so I see no reason to write an app or apps for science - biology, chemistry or physics!

I hope Doc Brown's science-chemistry pages will prove a useful and good revision e-learning website for revising AQA, Edexcel and OCR 21st Century and OCR Gateway GCSE Science, GCSE Additional Science, GCSE Biology, GCSE Chemistry and GCSE Physics. Hopefully, eventually! these revision guide summary revision notes will cover all aspects, learning objectives, items of all the topics, units and modules of the AQA, Edexcel, OCR 21st Century and OCR Gateway GCSE science courses. I also hope this revision site offers revision tips and encouragement and hope that you can do well in your exams!

Homepage of my website for high school-college-academy on-line Science-Chemistry Revision help since 2000

Although Doc Brown's website centres around UK science courses, the study notes and revision quizzes should prove useful for chemistry revision of any science course taken by 11-18 year old school-college pupils-students around the English speaking world. I've tried to indicate the US grade levels and other countries if supplied with the information. The site covers KS3 Science GCSE, IGCSE, O Level and A Level Chemistry AS A2 IB and enables free online student exam revision help notes and practice questions eg quizzes

 In using Doc Brown's chemistry website PLEASE FIND YOUR 'nearest' ACADEMIC LEVEL of the three choices above or below and PLEASE explore the ensuing links. You can save and use the MINI-SITE MAPS of Dr Browns chemistry website for each academic level, and also use alphabetical A-Z science site index and most pages have a Google site search dedicated to this site.

The site is written for three broad academic levels

"Doc Brown's Chemistry Clinic" website was www.wpbschoolhouse.btinternet.co.uk BUT is now known as "Doc Brown's Chemistry" hosted at www.docbrown.info and rapidly becoming "Doc Brown's Science" site as I branch out, as well as GCSE Chemistry, into GCSE BIOLOGY and GCSE PHYSICS revision notes too, in other words I'm aiming to cover, at least in revision summaries, all the GCSE science courses.

So, PLEASE update your links! The site is free to use on-line, and always will be and seems to work ok on all  iphone ipads netbooks epad tablet android systems NOT in apps format. Contact via  chemhelp@tiscali.co.uk.

How to revise chemistry? What is the best way to revise chemistry for examinations? Exam revision is a chore, and, there is no way round it, but remember that hard work pays off and the biggest resource, apart from your teacher, lesson notes, textbooks, internet etc. is YOUR potential ability to learn, AND developing a positive attitude to study, that enables you to work hard to succeed.

There is no magic revision method - quality time study - this is science not alchemy!
