CAREFULLY My 'A
level' chemistry 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. To return to this
page click on the <== back on the browser link bar. All the syllabus-topic-unit titles
are taken from the official syllabus. I do not have time to deliver extended
responses to email questions and do NOT ask for past papers. *
