Thanks for the clarification.
Some of what you’re saying makes a lot of sense, but there are also some misconceptions mixed in.
Most significantly, a MechE program is not a general engineering program that allows you to dabble in other disciplines. Some schools have First Year Engineering programs that give you exposure to multiple fields before you have to decide - that might be ideal for you, but I don’t think any of the schools on your current list work that way.
It’s true that MechE can have a strong design component. But to be honest, what you’re describing - particularly the passion for art - sounds more like Industrial Design to me. SJSU actually has Industrial Design - have you looked into it? All Design students start out in Design Studies; ID students are then admitted to Industrial Design by portfolio review. Design Studies does not have a high impaction index; it is possible that you could switch into this major:
(SFSU also has Industrial Design, and is still taking applications.)
I also don’t think study abroad opportunities are a good reason to pursue architecture. You can study abroad - and take arch history courses and the like - regardless of whether you’re majoring or minoring in architecture. (There are some architecture-specific programs abroad, but a minor wouldn’t give you access to those. Meaningful Architecture minors are relatively rare - Utah’s is an unusually good one. SJSU’s really isn’t.) Architecture has a high attrition rate, in part because it’s very hard for people to know what it will be like until they’re in it. This is why programs like summer intensives are so useful. The studio courses at West Valley are also quite good.
You seem as if you really need time and exploration to figure things out. There’s nothing wrong with this! But it’s all the more reason not to commit to an expensive school like UlUC. It might really be in your best interests to go to the other extreme and spend a couple of years at community college while you figure out what you really want to do. Right now, you’re hoping to keep a lot of options open by doing multiple things in college, but I don’t think it’s actually realistic to combine all of the things you want in the mix. You risk getting bogged down in indecision and taking expensive extra terms to graduate. Doing CC would allow you to “dabble” more, and even take a little extra time to figure things out, without blowing your college budget.
But if you think Industrial Design might be a fit, that path may very well be possible at SJSU. (From the website: " Applicants must indicate BA Design Studies as their major of first choice. All Industrial Design majors are admitted as BA Design Studies students. If you were admitted with a major other than BA Design Studies, please email us at design@sjsu.edu ) And I think you’d find a lot of community there, in a cohort that shares your passion for art and spends many hours in a shared studio environment. It might be something to consider.
Another SJSU major you’d be able to switch into, that might appeal, is Packaging. The name doesn’t make an exciting first impression, but it’s actually a very interesting and very well-paid field that combines a lot of your interests. SJSU: BS in Packaging
FWIW, SLO has a Packaging major too - it’s excellent but often overlooked and thus easier to get into than many other programs, just as it is at SJSU. Cal Poly SLO: Packaging Technology
One other thought… since you’re very interested in studying abroad, another approach would be to do a gap year abroad next year (i.e. with AFS - living with a host family and doing a “super-senior” year of high school), and reapply to better-chosen programs for the following year. Depending on how many AP’s you’ve already taken, you might be able to take more college-level classes during a year abroad, which would cover more college requirements and give you more of the elective time you are hoping for, to explore in college. I just mention this to say, you don’t have to wait until you’re in college, to study abroad - you could do it first, and buy yourself more time to sort out your plans.
