Last Year, Last Semester and All I want to do is graduate

So the university has decided I am not eligible overload. I only need to be over a half credit, it's a half credit. However, I don't have an 85% average overall or in my major so I’m not allowed.  I have overloaded every other semester of my undergraduate degree but this semester I have to have an 85% average or get permission from the dean of my faculty. This is making my life overly difficult when all I want to do is finish in April and graduate in June. This does not seem to be asking for too much I am a good student and always pay my fees on time.
