Unless you're considering law/medicine or some fancy professional/grad school at one of the Ivys, I would say where you do your degree at doesn't matter as much in terms of your long term academic and professional goals (even then, those who are motivated and have the smarts and the shits will get into those school). UMich and UVA are both solid schools to do it at so I would choose which school you feel you'd get the best experience at, not just educationally but in terms of actually living on campus and being able to network effectively.
In the end, the higher up on the academic chain you go, where you get your degree won't matter so much as who you worked for, what your capabilities are and who you got to know and connect with in your years in university, especially if your're considering graduate school.
Yeah, agreeing with this - the school you go to matters way more for graduate and postgraduate degrees than undergraduate.
For example, with a Bachelor of Science, the only thing that really matters is whether or not you can do research in your area of interest, so you have a platform to apply for PhDs etc.
just a bachelor of business for now, i'm looking to pick up international studies with a major in japan in my second year (missed the atar by like a point l0l)
Cool - assuming you plan to pick up a double major/degree, you can often take all the subjects you want anyway.
For example, at USyd the UAI cutoff for BSc (Adv) was around 96. However, you could take the advanced stream of subjects even if you didn't have that UAI. So you could do a non-advanced BSc, and take all-Advanced Chemistry etc., and then at the end of the degree, you could ask to be upgraded (or get upgraded automatically) to the Advanced degree.
For you, then, you'll probably have a bunch of business units as compulsory, and then some "free" slots that you can spend on whatever you want - if you can take the courses from the Int. Studies as your "free" subjects you may be able to get the combined program without the formalised transfer process.
