I’ve gotten into both, and I would rather go to CMU (higher ranking is the main factor here) except for the factor of cost. I’m an international student, so both are expensive, but CMU costs more. I would like to get more input on the cost of each and why I should choose one over the other - why CMU may be worth the cost or to choose UIUC just because of the cost.
Thanks! 
It’s hard to discuss value when we don’t know how much you’re paying for each.
CMU is generally more well-known internationally, which could prove to be a benefit in your home country. In terms of ranking, the difference is small and therefore completely irrelevant. They are basically peers in engineering.
CMU is a much smaller school and perhaps for that reason a better experience over all. It has a very strong CS program and focus. It’s also in a bigger city (Pittsburgh) and right next to a much larger university for social life.
I’d pick CMU over UIUC but whether it’s worth the extra cost is something only you can decide depending on your personal financial situation.
@insanedreamer Aah i see. Thank you so much!
What’s the cost difference? They are very similar academically for engineering.
@WildestDream @Dunboyne Cost of UIUC is between $48,000 to 57,000 while it’s $72,000 for CMU (yearly cost)
They are both excellent in your field. CMU offers smaller classes, better prof interaction for research/projects. Good internships/placement from either. I’m not sure CMU would be worth the extra tens of thousands from an academic point of view. Of course it depends how easily your family can absorb the cost difference.
Many internationals don’t seem to care much about campus culture, but research this. CMU is CS-focused, whereas UIUC will be more diverse in terms of interests (and motivation). Pittsburgh is not the same environment as Urbana-Champaign.
The reputation in your country is something to consider, too.
@Dunboyne Aaah I see. Thank you so much! You’ve given really incredible input.
