Question

How do I calcaculate my GPA on a scale of 4? What is the highest SAT score a person can get?

Answer 1

A-4, B-3, C-2

and the highest SAT score you can get is a 2400 (the new SAT)

Answer 2

On a scale of 4.0, add together the final grade you recieved in each of the classes you have completed thus far on the scale A = 4.0, B = 3.0, C = 2.0, and D = 1.0. Then divide the sum by the number of classes you took. This is your GPA on a scale of 4.0.

On the old scale, the highest attainable SAT score was 1600 (800 Critical Reading and 800 Math). Now it is 2400 (800 Reading, 800 Math, and 800 Writing).
