Find and write down your grade for each class.
Transfer your letter grade to a number grade. At Aiken Technical College, an A is a 4, a B is a 3, a C is a 2 and a D is a 1.
Multiply the numeric grade by the number of credit hours you received. So, if you have a B in a four-credit course, you would multiply three by four to get 12. These are your quality points.
