Changing major after applying, is it possible?

Hi,

I applied as a comp sci major to Cal Poly SLO. After reading up on the low acceptance rate with CS I was thinking about changing my major to SE if possible. I might be too late, but if this is possible who would I contact? Does anyone have any experience with doing this?

Thanks!

Contact admissions but I believe it is too late since acceptances will probably coming out any day.

From SLO website::
General guidelines

You are not allowed to change your major before you enroll at Cal Poly.

It’s too late. January 15th was the deadline for applicants to change their majors.
