Major Change

I recently got accepted into NC States college of textiles, however I submitted my application last November, and since then my study interests have shifter towards computer studies, which falls underneath the college of engineering.
In order to change my major, do they look at your high school transcripts again? Is it difficult to change? Or am I better off changing major after my first year?

Comp sci is very very difficult. Textile science has some computer stuff in it to produce fabric designs etc. Think of yourself as owning your own team sportswear, trophy award store-lots of business there.
