Your work experience is very good. Certainly being here at UofM may give you an additional benefit in the adcom’s eyes, but terminal degree and other masters programs (MD, JD, MBA) very much care about their class statistics, placements, internships and overall rankings on US News or whatever. They would probably admit a current UofM student with slightly less than median scores/GPA, but they will not admit a significant outlier. I think if your grad GPA is very high, you get a very high LSAT (median admitted at UofM is 169, which is >95 percentile), you have LOR’s from current UofM faculty and other good ones, and you have very strong extra curriculars then anything is possible. Also, DO NOT mention poor mental health in the addenda for poor grades. That is a “Kiss Of Death” in the eyes of the adcom (for example: if your undergrad courses caused a decline in your mental health, what’s going to happen when you’re taking graduate law classes). Always phrase your struggles with what you’ve learned from them in order to show growth and maturation- don’t just say working causes poor grades and leave it at that (although working to support yourself is definitely a valid reason).
