Which bitesize topics do I revise for C1C2C3 can't find?Watch
My exam board is OCR 21st century (I do triple science, looking for Chemistry topics 1 to 3: air quality, material choices and chemicals in our lives)
Can't seem to find where the topics are on the bbc bitesize website for revising just the first three (exam on thursday 9am) anyone know where to find JUST these ones? I found the C7 one but I don't need that til june.
Some C4C5C6 stuff: http://www.bbc.co.uk/schools/gcsebit...d_ocr_gateway/
