Having now finished my exams (So I know how they all went I am going to update my prediction (:O such a badman I know)). (I am Year 12)
Best Case:
Maths: A*
Physics: A
Chemistry: A
Biology: A
General Studies: A
Worst Case:
Maths: A (depends how many method marks I get, if it is just by answers I got right then I have >70 in all modules, but if my method wasn't clear it might drop)
Chemistry: A
Biology: A
Physics: B (didn't like unit 2, but in hindsight I am probably only worrying about 5 marks or so, which shouldn't affect it too much)
General Studies: U (To be honest I didn't revise and I hadn't done any past papers for general studies and I just sort of winged it, so I have no experience of what an A in GS feels like. Ah well.)
