Notes
The GPA is the credit-weighted average: the sum of grade points times credits, divided by the total credits. Rows with 0 credits are excluded. Universities differ in their conversion tables and rounding rules, so the result may differ slightly from an official transcript.
FAQ
- How should I enter pass/fail courses?
- Pass/fail courses are usually excluded from the GPA. Setting the credits to 0 keeps the row listed while excluding it from the GPA calculation; adjust to your school's rules.
- Why did my courses disappear?
- Entries are stored in your browser's localStorage. They do not appear in other browsers or devices, and clearing browser data removes them.
