If this on a 4.0 scale for gpa, with only three classes, with no specified value of the letter grades we can try.
An estimate for a C is about 73-76%, we can call it 74%.
An estimate for a D is 65-66%, which we can call 65%.
An estimate for an A is 93-96%, which we can call a 94%.
Now with only these three grades, we combine them. 74+65+94=233. Now we divide by 3, the number of grades we received. It about 77.66. Now compared to a gpa scale, a 77.66 is around the point 2.3.
All in all the GPA (grade point average) is 2.33.
Hope this help. Mark me brainiest!
