Use this spreadsheet to calculate what your GPA is by semester and also what your overall GPA is.
You can also play around with this spreadsheet to see what your GPA will be IF you get certain grades in the future.
How to use this spreadsheet
Step 1: Update the Key since every single college has a different conversion of their grades
Step 2. Update the Class, Credits and Grade columns in each of the Semester blocks (the 4.0 Scale column will automatically update)
