For example. If you’ve only taken 1 class before and got a C. That means your old gpa was a 2.0, If you get an A in a second class, it would increase your gpa to a 3.0 because you average your grades. you have a 2.0 for the first + 4.0 for the second class=6.0 divided by 2 clases=3.0

a=4.0

b=3.0

c=2.0

d=1.0

f=0

The more classes you have taken the more different your gpa would be. if you’ve taken 5 classes and you got all Cs and then you took a 6th class and got an A in it your gpa would be 2.3 because

5 classes multiplied by 2.0=10.0

+

1 class multiplied by 4.0= 4.0

= 14.0

divide 14.0 by 6(#of classest taken)= 2.33
