Like even if she says no what do I do about the first class I can't miss that or leave early as it goes for an hour and we are working on our 6500 systematic review. I cannot not be there. 

I would also have to go from my class back to my room set up and have lunch in the space of zero minutes. @Snowie 

I've heard she is hard with exams. However, she does not have an accessibility plan like I do. It's also a mid sem exam so it's not run by outside the uni staff with the end of sem.
