I've got an offee dor Msci theoretical physics here.
Did AS chemistry, maths, furthermaths (self-taught) and physics. Got AAAA. This year I'm doing the same 4 but A2s (self-taught myself furthermaths as well).
Since my offer is AAA, I'm confident of getting two As in physics and maths. Not sure about chemisty or furhrmaths. Do you think they'll be okay with AAB since I'm doing 4 A2s, one of which is totally self-taught?
Additional info: I got A*s in my chemistry unit 4 and 5 papers' mocks. I got E in the ISA, however. This is primarily because I'm color-blind and the first exam had lots of color observations. The second ISA exam, I worked my ass off, and still was just a mark higher. Having said that I need a ridiculously high A*s in unit 4 and 5 to pull an overall A off.
Also, for furthermaths, I can manage an A* in M2, an A or a B in FP2, and a B or a C in M3. So, an overall A is basically out of the question.
...or just paranoid?
