We accept students for A-level Sciences if they have C in the individual subject or a BB in double science. Although management says the opposite, I'm personally far happier taking on a BB double science student than a CCC triple science student. In Biology, I'd be looking for, if not a B in GCSE Bio, then a C plus a pretty good English Language grade. If the Chemistry grade is good then I can do something there. Bio is sometimes thought of as a bit of a doss subject because of the lack of maths in most specifications, but Physics would ask for a B in Physics and Maths no questions asked. I would echo the earlier post - a C at Foundation is wholly different to a C at Higher level. When my colleagues imply that we shouldn't accept any double science students I remind them that I was a double science student and it was good enough for Cambridge University. I think more than triple science, mastery of whatever science you do is important at GCSE. C grades do not show mastery. And yes, the majority of my C GCSE students in A-level have the battle of their lives on to get through AS with anything above a D.
