Stony Brook Midyear Grades?

Stony Brook University emailed me a couple weeks ago saying my application was incomplete because I still needed to submit my midyear grades. When I called the school’s undergrad admissions, the representative said that midyear grades aren’t required but if I was asked of them, I should send them in. Now I’m kind of nervous, is this a good or bad thing? My stats are 92 gpa 1360 on the new sat 29 on the act.
