Question

A student receives his grade report from a local community college, but the GPA is smudged. He took the following classes: a 2 hour credit art, a 3 hour credit history, a 4 hour credit science course, a 3 hour credit mathematics course, and a 1 hour science lab. He received a “B” in the art class, an “A” in the history class, a “C” in the science class, a “B” in the mathematics class, and an “A” in the science lab. What was his GPA if the letter grades are based on a 4 point scale?

Answer 2

Assign a number to each grade based on the 4 point scale (I'm English and so don't want to make a mistake by trying myself). You want to find the relative mean of the grades he received. To do this, I would multiply each grade by its number of hours, add them all together and divide by the total number of hours for which he took classes.

If A+ were to equal 4, A to equal 3, B to equal 2 and C to equal 1, you would get a GPA or 2.
