Hi guys, can someone please help me out. I am studing to write IGCSE Physics and Chemistry for the second time, the last time I wrote was 2 years ago. I have unfortunately lost the CD's that give me the answers for the end of Chapter questions. The books are Cambridge IGCSE Physics by David Sang. And Cambridge IGCSE Cehmistry by Richard Hardwood and Ian Lodge. I bought them in 2012 so it will be the 2012 versions. If someone could upload them or find a link or something, I have looked everywhere.
