So after talking with some of my peers at UMich, it appears that the selectivity for the three main schools (Ross, LSA, CoE) would go
OOS Ross > OOS CoE > IS Ross > OOS LSA >= IS CoE > IS LSA
(>= means greater than or equal to)
Obviously, there is not data I have to back this up.
Does this seem fairly accurate to some of the senior members of this CC community?
If you’re in-state, apply and hope for the best. If out of state, consider if you would be able to afford Michigan if admitted (offers little to no financial aid or scholarships to out of state students IIRC, but check the website,) and then like an in-state application, apply widely (safeties, matches, and reaches) and hope for the best! 
Choose the school that fits the “story” your application’s trying to tell. If an Admissions Officer was to look at your essays, interview, extracurriculars, courses etc, would they show, not tell, your interest in x or y field? This is more important than the slight discrepancies between each school’s admissions rates, as Michigan as a whole is difficult to get into. Keep in mind that if you end up applying to a different school than the one you want to attend, there may be specific requirements or a competitive application process to transfer, if it’s allowed, so make sure you research that deeply beforehand.
Hope that helps!
Where would School of Kinesiology fall in the relative selectivity?
Looks correct to me.
I’d say probably as selective as Ross or CoE, since there are only about 166 (last count I’ve seen) seats in each class and many of those seats are reserved for athletes.
@sushiritto It’s selective in that the acceptance rate it probably low, but the applicant pool is much weaker than the other three from my experience on campus. Nursing/Kinselogy are niche programs that don’t require GPA/SAT/ACT to be as high as the others. Though I agree in that since there are limited seats, it will naturally be selective
You’re correct, acceptance rate is low and the applicant pool is weaker than BBA/CoE/LSA. You can throw SMTD in there too since their applicant pool is weaker than the “Big 3.”
