B7 Pre Release 2011

Showing 1 to 3 of 3

does anyone know any types of questions that may come up on the B7 OCR 21st Century Science Paper this year regarding the pre-release on wrinkle cream?

I'm taking that exam myself and I am very worried cause I find B7 very hard. If you go to the OCR website you can find past papers on B7 but the pre-release will just be on the text so I suggest putting some research into anti-winkle cream. I guess you will probably get questions like "How can scientists be sure that this Winkle cream is safe, what things could be done to assure this?" But I shouldn't worry to much about the pre-release as its only like 15 marks of the whole paper.
