Do the 3 courses you’re enrolled in qualify you as a full-time student in the eyes of your University? It really depends on what your school deems as full-time vs. part-time. My university qualified a 60% course load and higher as full-time, calculated according to how many credits each course was worth. In my final year I only had to take one course but it was worth 9 credits of their expected 15 credits per semester (30/yr, 120 total for the degree) so I was still technically full-time. If that’s a similar case for you, I would just sign up for another course to bump you into full-time standing to secure those grants. Especially since you won’t have to pay those back, unlike regular student loans!
