can anyone explain how the science gcse's work. DD1 is in year 10 and has chosen triple science and has been told that if they do well can end up with four gcse passes ie chemistry, physics, biology and core science. I thought core science was just a dip into each of the sciences and was intended for the non=scientists and is the compulsory bit. How can they award a certificate on work that is already covered by the separate sciences or is it just a way of collected points
