I KNOW i cant add anymore courses but will they make an exception If I email the department . Has anyone tried this before

they will never make an acception but they might make an exception. (but actually I don't think they will)

Go talk to your academic advisors for your faculty. Depending on the reason for being late to drop your courses, they might back date it for you.

One of my friends did get to add a course after the deadline but she had to go talk at the office of associate dean and she had to have a really good reason.

I was able to change after the drop add date but only because a seat was reserved for me and the academic adviser told me afterwards :/
Just go talk to an academic adviser and see if they can do it for you
