Part 2. How to calculate the Semester Index necessary to change your Graduation Index to a desired value.

1. Use this to calculate how your graduation index will change based on the semester index you receive.
2. You will need to know how many hours and points you have before this semester's grades are added to your graduation index. You can calculate those in part 1 or in some cases you can read them off your most recent grade card.
3. A grade in a second enrollment in a class replaces the grade and credits of the first enrollment in the class when calculating graduation index.
