So "credit hours" roughly corresponds to how much time a course meets for or requires鈥攆or example, a course that meets for 40 minutes a day would be worth 1/2 of the credit hours of a course that meets for 80 minutes a day. If all of your classes meet for the same amount of time, then you can just say they all take the same amount of credits (because GPA is an average, the actual number you use doesn't matter, just the ratio from class to class).

Beyond that, you can calculate GPA by taking letter grades鈥攊f you receive those鈥攁ssigning them their corresponding value on a GPA scale, and averaging those numbers. These are those values on a 4.0 scale (the standard)

A+ = 4.3

A= 4.0

A- = 3.7

B+ = 3.3

B = 3.0

And so on. A C is a 2.0, D is 1.0, and F is a 0.0. The + or - grades are each a third of the way between. An A+ is a 4.3 on a 4.0 scale because only some schools even award A+s, and so it's higher than the "maximum" of this scale.

So roughly, what you should do is assign each of your final grades a value and then average them, and that should give you a rough approximation of your GPA.
