AS/A2 CIE Tips

I am writing these notes in digital format as a method of revising for the courses I am taking – AS/A2 Chemistry, AS/A2 Biology and AS Physics. *UPDATE* After time, I also understood that in order to get As extra work is required – I have added a few things worth reading here and there. Feel free to browse through the notes. They may include questions form past papers, for which I could not find any answers in the CIE Books.

The notes are made with regard to the 2014 (AS) and 2015 (A2) Syllabuses.

 Table of contents containing Biology, Chemistry, Physics, and additional websites.
