Re: OCR A Chemistry F324 Rings, Polymers and Analysis Thu 26 Jan 2012I use: http://pastpapers.org/chemistry-a2-papers and http://www.sci2.co.uk/chemistry.html(Original post by andrewpeters)
Could anyone link me to where I can find all the legacy/old past papers? I've seen the ones on the OCR website but they're in the form of a zip file and it's all mixed up with other irrelevant files...
Some of the files don't work, not sure why but most of them should be there. Hope this helps! -

Re: OCR A Chemistry F324 Rings, Polymers and Analysis Thu 26 Jan 2012Oh okay thanks, I have an inconsistent mark scheme from my college which is making it difficult to know which is right!(Original post by Robpattinsonxxx)
