Ditto, what csdad2 said. I think it’s great you are beginning your research early. I’m in the western Chicago suburbs and have two children currently attending UIUC…a junior and freshman, both in business. Their experience has exceeded our expectations.
Since you are instate, you are probably aware of both the pros and cons of the school so I’ll refrain from mentioning the opportunities there. I will mention something we found helpful when we were going through the college search process. We encouraged our children to focus on skill building in high school while thinking about possible careers.
In that respect I would suggest you check out your local community college. Ours is COD and they had a presentation that was very helpful for my (then high school) son. He is strong in math and science, who was considering engineering. They held an evening presentation with engineers from different engineering areas. Each spoke about their background and what they do in their job. Topics included salary and paths for advancement. At the end there was a question and answer period.
Later, this engineering presentation was a great opportunity to discuss goals and expectations with our son. Not only in regards to engineering, but the approach to take when considering any major/future career. And yes, he ultimately chose business over engineering. Good luck!
