Yeah, that doesn't make sense - it's of the form with true, and false so that will always be false. What's the actual question?
12. If I got

A* in C3
And
A* in C4
And
B in S2

(Also got an A in AS maths)
Is that an A* overall?

Yh
14. Just finished my 4th C4 paper and scored 72/75 -> 96% ums = A*

I should have really scored 74/75 stupid mistakes.
So far I've scored: 86, 87, 96, 96 and still plenty of past papers to do.

We're all gonna make it!

I would have thought you would use parts.

Oh yeah that'd probably work, I didn't think to use that because it was in one of the earlier exercises before parts.
