Another thought. Scholarship isn't just about the grades. It's about not skipping class and studying too. During finals, or when lots of people have mid terms, arange for study breaks. Lots of coffee and snacks and time to just relax for an hour or two.
Our campus was unhoused so we would just reserve a meeting room or classroom for study breaks.
We did something, that I don't think will translate to guys to well, called "Don't kill the dove" or "Don't break my heart". We'd have a cutout of a dove or heart (SK symbols) and it would be passed around the room. The sisters had to punch a whole in it for each class she skipped the week before. The goal was to not have a completely destroyed dove/heart by the end. It helped visualize how skipping classes can hurt you and the chapter.
