Since you asked for advice, I’ll chime in. People can share their experience and opinion, but we don’t know you so we can’t really answer your question…“which school would be better for me?” I think the schools are comparable. The school can assist you in reaching your goals, but ultimately your ‘success’ will depend on you…your aptitude, your attitude, your focus, your drive, etc.
So this is what I suggest. First, I would look at the total cost for your desired undergrad degree…sometimes the per annum amount can be deceiving…UIUC at $52,000 versus $200,000 (probably closer to $240,000) at U of M. Frankly, in my opinion, Michigan would not be worth it. I understand ‘not wanting to base your decision on money’, but unfortunately it’s what adults often have to do. Making compromises based on your wants and needs is a fact of life. Consider how/what your future self will think and feel.
^^ Oh, I just saw your post that your mom is willing to pay $20,000 per year…ask her directly if $50,000+ per year is even feasible. She may be like my husband and me. We could afford Michigan for our son, but frankly didn’t want to fund that option when he was accepted at UIUC (also, instate for us). In our mind, a quarter of a million dollars for an undergrad degree is ridiculous.
Second, I would research your AP credits at both schools. We found Illinois to be very generous in awarding credit…without penalty. Whereas at Michigan, if you take the AP credit, it can bump you up to the higher tuition level, making your degree even more expensive. (Note: I don’t know if this is still true…my son was looking to attend in the Fall of 2015, so they may have changed their tiered tuition based on credit hours.)
Lastly, I would plan a visit to UIUC when school is back in session. Make an appointment and shadow a student. Go in with an open mind and realize it makes the most financial sense. http://engineering.illinois.edu/admissions/visit-campus/
Btw, my son and daughter both attend U of I. They went to a west (Chicago) suburban high school that sends around 40 students per year there. They would tell you they don’t feel like it’s an extension of high school. They rarely see most of them…and when they do, it’s not a bad thing. Your mindset will affect your happiness in this matter.
I’m tired so I hope this post made sense. Good luck with your decision!
