Missed the deadline of the Japanese Placement Test

I was looking through courses (first year life sci student), and I realized I missed the placement test deadline BY ONE WHOLE WEEK. I'm not sure what to do now, because I informally studied Japanese in high school (and it also kind of fulfills by breadth requirement), and I kind of feel like an asshole if I email the East Asian Studies Department now. Should I just hold it off until the winter semester or should I attempt to email to get in, even at such a late deadline?
