uiuc major college problem

I was just checking my uiuc application status. I applied for chemical and biomolecular engineering. I realized that it was under college of liberal arts and sciences. But I would like to change my major and get into college of engineering. Can I do that? And regarding my acceptance, is it easier to get into college of liberal arts and science than the college of engineering.

Your program is an ABET-accredited engineering program. Look at the UIUC Engineering site. The program is jointly administered by both colleges. Call admissions, or the program office directly, if you have any questions.
