What grade would this be??

So I do modern history and the overall grade is made up like this
Paper 1 = 37.5 %
Paper 2 = 37.5%
Controlled assessment = 25%

I need to know what my overall grade would be

I think I'll get a b on paper 1
A d on paper 2
And I got an A* on the controlled assessment
What will be my overall grade??? Thanks.

If you were to assume each mark as the midpoint of each grade boundary your grade would be a B:
0.375*55+0.375*75+0.25*95=72.5

If you were to assume each mark as the midpoint of each grade boundary your grade would be a B:
0.375*55+0.375*75+0.25*95=72.5

That can't be correct bcos 55 marks isn't a B?

55% was the D, 75% was the B, 95% was the A*
