Applying for a Specific Program

On my application I selected plant science as my intended major which is in the school of agriculture and natural resources ,but if i wanted to change my major to biological systems in the school of engineering would I be able to do that? I don’t know how changing a major choice across departments works. Will I be admitted to a particular department such as the college of engineering or will i chose my major AND department if i go there.

I don’t know about changing majors across departments, but as far as admission, this is an excerpt from my DS acceptance letter:

Doesn’t say anything about changing colleges/schools before registration but I would definitely call Admissions about it. You want to be able to register for the right classes during registration. I don’t recall it being a big deal to change majors or schools later on either, but my experience is a few decades old.
