Switching Majors

I have recently been accepted to UCSD as a pharmacological chemistry major. I submitted my SIR 2 weeks ago, under the impression, I would be able to switch my major to molecular biology, but as of March 30 it became a capped major! Is switching my major still just as easy as clicking a button on my portal? Or will it be hard and competative like engineering majors?

I would contact admissions about your question (s) since the other capped majors require several pre-req courses to be taken before switching.
