1st draft of my unofficial support links for the course

AQA GCE A2 6421 CHEMISTRY

AQA GCE A2 advanced level chemistry course

My unofficial support for this AQA A2 advanced level chemistry syllabus-specification

Each topic or unit is linked to potentially useful sections on this site

 READ CAREFULLY  PLEASE remember that despite the fact that my 'A level' chemistry notes are far from complete, and as yet, do not even cover all the basics I think there is enough to start an unofficial support page. By clicking on the text and [ORGANIC], [INORGANIC], [PHYSICAL-THEORETICAL] and [useful GCSE notes] icon links you should find things to help on a particular topic.  The notes-quizzes are not just for your particular syllabus, but are designed to cover, eventually, any Chemistry in UK based advanced level pre-university chemistry syllabuses.

 READ CAREFULLY  When you follow a link you will find some useful information on the web page about the topic you are researching. Sometimes the link goes straight to the relevant paragraph but otherwise use the sub-indexes of key words or headings at the top of each page. To return to this page you must click on the <== back on the browser link bar. All the syllabus-topic-unit titles below are taken from the official syllabuses which you can download from the appropriate site.

 READ CAREFULLY  My advanced level chemistry pre-university research-information-revision notes are ALL are being slowly revised and extended-updated to cover any 'A level' chemistry BUT I do not have time to deliver extended responses to email questions and please do NOT ask for past papers.
