How competitive is Cat State Fullerton's B.S. mechanical engineering major?

My CSU FULLERTON application is pending right now because I had to send them my college transcripts (not a transfer, going in as a freshmen).

Right niw, they’re reviewing my application as a Biological science major, but I was thinking about changing it to mechanical engineering, but I know engineering is a pretty competitive major.

I was wondering if I should change my bio major to mechanical engineering right now before they make and admission decision, but I’m afraid if I do that, my chances of getting in will do down…

Any advice would be appreciated.

God Bless,
K
