This sounds stupid and I’m probably overthinking it but I graduated in July of 2020 but the last day of school for me was may 15th I believe. Do I say that I was a full time student ?

Yes, if you were enrolled as a full time student for any part of at least five months during the year, based on the number of credit hours you're taking. ... However, the months don't have to be consecutive.

 

Full-Time Student

A full-time student is a student who is enrolled for the number of hours or courses that the school considers to be full-time attendance.

To qualify as a student, the person must be, during some part of each of any five calendar months of the year:

1. A full-time student at a school that has a regular teaching staff, course of study, and a regularly enrolled student body at the school, or
2. A student taking a full-time, on-farm training course given by a school described in (1), or by a state, county, or local government agency.

The five calendar months do not have to be consecutive.
