What to call Michigan in essays

I am sure I am not the first ask, but what do you call Michigan in the essays. I don’t want to write University of Michigan ten times, so what do people normally say? Some of these I have heard, others I haven’t: UMich, UMichigan, UM, Mich, Michigan? Anything better?
Thanks.

I think it comes down to tone, if the sentence is formal use “The University of Michigan” otherwise any of the others will work. In all honesty, I do not know if it even matters all that much. I just went back to check and in my “Why Ross” essay from last year I used the word “Ross” 11 times. ?

Anything but “OSU” or “THE Ohio State University” should be acceptable.

@Publisher… That’s great ??! Lol

You only really need to refer to them like once. Then your essay should be about yourself on campus, why your a good fit, etc. Not sure why you would repeat their name. The essay is about you and them. They know who they are… Make sense?
