The OP’s SAT and ACT math scores are not particularly low in the general context of engineering students and engineers (there are lots of engineers who graduated from less selective schools after being admitted with SAT or ACT math scores lower than the OP’s), although they could be detrimental when applying to the most selective engineering majors or divisions, including some of the current list.
Oh they are don’t worry, just wanted to see how I fare at these out of state schools. I’ve already been accepted at a few of my safeties, Iowa State and Michigan State.
"My brother, who is my legacy at Georgia Tech, actually was accepted into their CS program back in 2013 with a 29 ACT (he’ll be graduating this month ). I do realize however that the profile of students has increased quite a bit since then, but it helps "…
Don’t look at the overall posted score averages. They aren’t used to admit students and those averages fluctuate regionally on a yearly basis depending on interest in the college.
College admissions offices divide up the country by regions and admit the best candidates from that region. They do this to spread the college’s brand around, increasing the college’s profile. It’s marketing. The region may be as big as a state (Idaho) or as smaller as a city (Miami) or even large suburbs. They want to get X number of students from each area. Kids from within each region are competing against each other and are not competing with kids in other regions. If you are in an area with low interest in a particular university the standards for admission will be lower. Likewise if you are at a school with high interest in a particular college and multiple students ranked above you are applying you don’t have much of a chance.
So in your case, you are competing against other rural Michigan students.
Besides scores, grades and accomplishments the determination of what is the best candidate also relies on the connections the kids have to their community. How many people will find out that Jimmy/Jenny went to college Y. It’s marketing.
ACT 31 is a good score, but may be not good enough for good engineering schools. It is only around the 25th percentile at UMich and most majors at UIUC. More important, UMich pays particular attention to the Math score. The average is around 34 and the 25th percentile is around 32. I know an in state student got rejected by UMich even with ACT 33 and 3.8+ GPA.
Michigan State has (or at least used to have) a fine mechanical engineering program. Engineering is not like business or law or a lot of other majors where there is a big demarcation in job opportunities between the elite schools and everyone else. I know plenty of folks who turned down very prestigious engineering schools (including MIT) to go somewhere else in-state to save a lot of coin, and they have had spectacular careers. Tim Cook went to Auburn - which is a fine school, but not quite elite. There are a lot of top engineering managers at a lot of top companies from schools like that. I would worry a lot less about an elite school, and a lot more about a “good school” which excites me, where I see opportunity, and where I think I would “fit it” and will make me want to work hard to be my best. Good Luck!
@Jawtek82 Yeah I think this thread has made me realize that I may have been too caught up in hype and prestige. I think about where some of my coworkers graduated and it’s a pretty diverse crowd: MSU, UMich, Iowa State, Ohio State, UIUC, Cincinnati etc. I’ve sought some of them out for guidance and all of them have more or less told me the same thing. Engineering curriculums are so similar across the nation that it pretty much comes down to where I feel the most comfortable and most importantly: how much I put into it. At the end of the day, the Cincinnati grad is working the same position as the Michigan grad.
Let’s say I do get accepted at UIUC or Berkeley. In the short run maybe I have some sort of marginal advantage, but over the course of a career, as long as I have an engineering degree from a decent college, it doesn’t really make a huge difference.
Thank you to everyone for their input and guidance.
Looks like despite my “excuse” those schools thought I was good enough 
Mechanical engineering requires some intensive physics courses… which is a LOT of math. Your SAT math score is 680… meaning you are pretty weak at the subject. On the other hand, you had a really good reading score on the SAT. Maybe something that integrates reading skills would be a better major. Also, your AP physics score was a 3. That is definitely going to hurt if you want to get into engineering.
IMHO I feel like you should rethink what you want to major in. Feels like you are just forcing STEM courses and related clubs upon yourself. You don’t have to be an engineer in order to be successful in life.
@NotABonobo Well this is awkward… Check the original date of the post and look through my post history. Long story short I got into UIUC and Michigan 
Lol, congrats. Haha, did not even see that. Good luck in college.
You are competitive for all of these schools. Your stats and ECs are pretty good, and your URM hook will probably help your application
UMich may offer you the summer bridge program. Be consistent with your info. You reported as OOS on the thread while in-state in this thread.
@billcsho Yeah I’ve lived in Michigan for a little over two years now (lived in Iowa before) and thought I’d qualify for in-state, but due to some circumstances I’m an OOS applicant
You may still be benefited from attending a high school in rural Michigan area though. Also, for tuition purpose, you may be considered in state at UMich by going to high school for 3 years before graduated from it. Nevertheless, I have heard they may have changed the policy last year.
