Will a legacy push me over the top?

Hey guys,

I am just a sophomore in high school in NJ, and I recently fell in love with the UM campus. I’d like for you guys to check my grades and ECs along with my legacy to see if u think I have a good chance.

** IDK if this helps at all but my high school is a top 5-8 HS in New Jersey, and has been ranked as high as 2 in the country. My school is extremely competitive with great teachers, but it also hard (which explains low-ish gpa) so does that help?

Gpa: 3.7 UW
Legacy: dad attended UM, grandma attended UM, both great grandparents attended UM. So there is a clear pattern.
EC:
100+ hours of volunteer work just last summer at nature center
Job this upcoming summer at nature center
varsity soccer, JV basketball
club soccer
babysitting
trombone for 5 years
probably more but I can’t remember rn lol

So, based on that, what would you say my chances are at UM? What would I need on sat/act to give myself a great chance?

thanks

UM means?

Maryland
Minnesota
Michigan
Mississippi
Montana
Missouri
Massachusetts
Miami

Michigan

A 2100 will be okay. A 2200 will be great for Michigan

alright, do you think I’m on the right track with gpa and ECs? And what about the legacies?
