Edexcel a2 chemistry revision for the may/june 2012 exam :)

how much do you think you need to get the full 120 ums?????

Hi, I'm taking Edexcel Unit 4 and Unit 5 in June 2012. Starting making revision notes/mindmaps now using the Edexcel student's book, George Facer Book and CGP book.

If anyone's interested in some good online resources for A2 Chemistry:
-Chemguide
-Knockhardy
-Rod Beavon's pages (chief examiner)
-Tips on surviving your Chemistry A-Level, written by a successful student

I'm doing Unit 5 in class at the moment - doing electrochemistry/redox and organic synthesis. Transition metals, arenes and organic nitrogen chemistry all done!

Good luck!

Hi
