Yes. With Science you can either do applied (were you only take one exam, and you do coursework instead of all the exams the other sciences do. You do around ten or eleven pieces of coursework, you get two GCSEs for applied and Double), Double Award (you do nearly all exams, and no coursework, i think) or Triple Award, where you get three GCSEs and that's for the people who want a career in science, for example, a vet. You do three different subjects; Biology, chemistry and physics. In the other sciences these are just areas you study, but they are individual subjects in Triple. Sorry if that's confusing!
you can do three sciences at gcse (called triple science - very adventurous) where you do biology, chemistry, and physics seperately
