Question

John needs to know his GPA for his first and only 12 credits. His courses and grades were: 4 credit C (2.0), 3 credit D (1.0), 5 credit C+ (2.5). If he takes another 10 credits and gets a 2.5 average for those what will his new gpa be?

Answer 1

You multiply the credit hours by the grade for each course. You add this number up and divide it by the total number of credit hours to obtain the first semester average GPA. 

((4*2)+(3*1)+(5*2.5))/12

To do this problem with the additional 10 credits, the equation will look like this,

 

((10*2.5)+(4*2)+(3*1)+(5*2.5))/(10+12)

 

10 credits of a 2.5 GPA represents the (10*2.5) term of the equation.
