Question

One common system for computing a grade point average (GPA) assigns 4 points to an A, 3 points to a B, 2 points to a C, 1 point to a D, and 0 points to an F. What is the GPA of a student who gets an A in a 3-credit course, a B in each of three 2-credit courses, a C in a 4-credit course, and a D in a 3-credit course?

The mean grade point score is ?

Answer 1

$$ \begin{array}{l} \text { Grade point score }=\frac{3 A+3(2 B)+4 C+3 D}{3+3(2)+4+3} \\ =\frac{3(4)+3(2(3))+4(2)+3(1)}{3+6+4+3} \\ =\frac{12+18+8+3}{16} \\ =\frac{41}{16} \\ =2.5625 \end{array} $$
