What would my gpa be?

Colleges would consider 92-99 an A, 84 - 91 a B, and so on. There's no direct conversion from an overall percentage to a GPA; you must do it class by class. Convert each percentage in each class to a letter grade, convert that to the 4.0 scale (A = 4.0, B = 3.0), multiply it by the number of credits each class was worth (you didn't list that here), add them all up, and divide by the total number of credits to find your overall GPA.
