Do your best to match up your average GED score to an estimated GPA below:
GED Score Estimated GPA
Below 300 = 0-1.0
300-400 = 1.5-1.9
401-500 = 2.0-2.9
501-600 = 3.0-3.4
601-700 = 3.5-3.7
701-800 = 3.8-4.0
From the example above, an average score of 460 would be equal to about a 2.6 GPA. If you don't have any section value or total score, then contact your university/college from where you took course. Some colleges have their own methodology of calculating GPA.
