1. Can anyone tell me where can I find the materials ( e.g. books or past paper) about the Chemistry Unit 3 and 6 (international) respectively?
2. Where can I find the past papers and solutions (Unit 3 to 6 of 2009 Jan; Unit 2; Unit4 to Unit 6 of 2009 June and the whole units of 2010 Jan)?
I have already find the forum (xtremepapers.net) and freeexampapers.com, but I can't find it. Thanks a lot!
