 READ CAREFULLY  My 'A level' chemistry revision notes are far from complete BUT by clicking on the links for [ORGANIC], [INORGANIC], [PHYSICAL-THEORETICAL] and [useful UK based GCSE/IGCSE revision notes] you should find things to help on a particular topic.  By following a link you will find some useful information and use the sub-indexes of key words or headings at the top of each page.

I do not have time to deliver extended responses to email questions and do NOT ask for past papers.
