Doc Brown's Chemistry Clinic - chemistry revision notes for the Edexcel A level chemistry course from September 2015 - UNOFFICIAL HELP for this Edexcel A level chemistry UK based Advanced Level Chemistry Courses

First examinations in the summer of 2017 for A level (Edexcel GCE A-level chemistry code 9CH0)

Selected HELP links to my Advanced Level Chemistry revision notes based on the three index pages ...

[ORGANIC CHEMISTRY] * [INORGANIC CHEMISTRY] * [PHYSICAL-THEORETICAL CHEMISTRY]

PLEASE NOTE for students doing the Edexcel A level chemistry course.

  1. My notes are not in anyway to be an alternative to your teacher, your textbooks or lesson notes for the Edexcel A level chemistry course.
  2. BUT, sometimes a different presentation of a topic in your Edexcel A level chemistry course can help your understanding.
  3. SO, a little 'study supplement' to your academic diet is freely available online via doc brown's website.
  4. Scrolling down the page, you will find the links to my notes are organised to fit in with topic/unit/module headings in the order specified in the official syllabus-specification for the Edexcel A level chemistry course.
  5. More links will be added over the next year and the A level chemistry notes expanded to cover more topics in the Edexcel A level chemistry course.
  6. When following a link to potentially useful study material, also check out the sub-index links at the top or bottom of page.
  7. You will find the [Google Search Box] at the bottom of the page very useful for looking up aspects of your Edexcel A level chemistry course.
  8. I don't really have time to deliver extended responses to email questions, and do NOT ask for past papers for the Edexcel A level chemistry examinations though I will do my best to provide links to past papers as they appear on the Edexcel A level chemistry exam board website.
  9. I don't mind queries or comments on my web pages irrespective of their usefulness to the Edexcel A level chemistry examination course.
