Look at the 1st year requirements checklist for Industrial Design (http://archdesign.vt.edu/images/IDS%...nal%202010.pdf) and compare those classes to the ones you would do as undecided. How different would they be? The answer to that may also depend on what AP credits you are bringing in.
From what I see elsewhere on CC Industrial Design is quite a hard major to get into so you might want to stay there and decide later.
Congratulations on your acceptance into a very difficult competitive major at VT. My son is finishing up his first year in Industrial Design and really seems to enjoy the design process so far.It is time intensive, but he has managed his time and has had a great experience at VT.
Based on his experience, I would suggest that you stay in the program for now-it is extremely difficult to transfer in. If you really do not like it-much easier to transfer out. PM me if you would like to ask my son questions about the program.
