Is transferring to a target school from an NT after freshman year a good idea?

Right now I'm in a gap year between HS and college (a nontarget) and I've been spending it working and trying to find ways to do things in the financial field that would look good on a resume. But unfortunately, in HS I really did not try very much. However, I did get accepted into a decent university, but it is still nontarget. During the course of this gap year I truly realized how incredibly important it is to work hard in your education, therefore, my plan is to maintain a higher GPA and join some business and finance-related clubs during freshman year so that afterwards, I may transfer to a more prestigious school. But I am just wondering if IBs care if you transferred, and if this transfer can interfere with internships. I guess freshman year is early enough to where you can still figure things out, but I'd rather that assumption be confirmed or denied by those with experience and knowledge.
