How hard is it to change majors in CALS?

I recently was accepted as an Environmental and Sustainability Sciences major into Cornell CALS. However, I’ve been increasingly interested in switching to Biological Sciences(also within CALS). It appears that changes majors is more of a process here than at other schools, and was wondering how that process works. Thanks!

Are you a Sophomore? I don’t think any freshman is directly admitted to a major. You would be able select your desired major later – so if you are a freshman you should be fine.

Not in CALS, they admit by major.

Not sure of the exact process for CALS, but from what I’ve heard anecdotally it’s pretty easy to switch majors. My friend switched majors in CALS the summer before she even started. Email your advisor when you get assigned one.
