Thankyou, i know this site very well and have already seen this page, it does not require the specific information i am looking for, if i explain here many somone may have some idea of what i am talknig about and if not, please carry on with previous convosations.
Basicly i am entering my final year at high school or secondary school and the science cource changes from a structured physics module, bioligy module and a chemistry module (each carrying GCSE exams as explained above) and all three is equil to one GCSE in science, for the second year (the one i am entering) we have a choice to do additional science, which is the same as above but more advances or additional applied science, this is three different modules, Food science, Forensic science and Sport science, with mainly coursework and one exam at the end counting towards a GCSE as well, i just do not know which one i need to take or weather it doesn't matter.
