    Hi I'm doing a2 biology practicals next week for OCR. Pretty much all we have been told is the subject areas, which for quantitative is enzymes and for qualitative is the chromatography of photosynthetic pigments.

    I'm resitting a2 this year and last year i did really badly in the practicals so I'm really panicking, so if anyone has done one of these practicals recently or could give me any further details on either of the practicals I would be eternally grateful!!!!!

    Thanks!!

    You have to fill in 2-3 tables with regards to Rf values and identifying pigments. All info you need is given, but put answers to 1 d.p and in mm. I can't really remember the questions but they look for you talking about absorption and reliable results! Sorry I can't be of more help
