Frequently Asked Questions

What is a 4.0 GPA scale?
The 4.0 scale is the most common GPA scale in the US. An A is worth 4.0, B is 3.0, C is 2.0, D is 1.0, and F is 0. Plus/minus grades adjust these by ±0.3 or ±0.7.
Is a 3.5 GPA good?
Yes — a 3.5 GPA (B+/A- average) is considered strong and is above the national college average of about 3.1. Many graduate programs and scholarships require a minimum of 3.0–3.5.
How is cumulative GPA calculated?
Cumulative GPA = Total Grade Points ÷ Total Credit Hours. Grade points for each course = grade value × credit hours. Add all course grade points together and divide by total credits.
