I am already manually filling in all of the classes that I took from freshman year to senior year. Am I supposed to be repetitive and add those same courses to the core requirements section?
Yes, you should fill out both sections according to the instructions on the application. The Core Coursework section is where you just indicate which core courses you have taken, you do not have to provide as much detail there as in the Additional Coursework section. For Core Coursework, you simply select the appropriate options from the dropdown menus to fill out the entry. For Additional Coursework, you will want to make sure that you fill everything out to match your transcript.
The detailed directions on the application should walk you through the process, but if you have any other questions - feel free to reach out here or contact our office: oafa@pitt.edu or 412-624-7488.
