There is no problem, unless the wife has issue being in second place. 'C' is considered average, while even a 'B-' is considered above average, a 'B+' is considered well above average, so the wife should revell in the fact that she is above average, even if her husband has surpassed her.
4b
b+b+b+c+c+c+c =3b+4c
3b
b + a + b - a = 2b
its B
A grade point average of 3.35 is about a B plus on a 4.0 scale. On this scale, a B grade is 3.0 and a B plus starts at about 3.33.

4b.
The scale can vary based on the school. In most that would be a solid B.
4b
b+b+b+c+c+c+c =3b+4c
b + b + b + c + c + c + c = 3b + 4c
a-b+a-b+2b+a = 4a
3b
b + a + b - a = 2b
It is: b+b+b = 3b
