Should I contact the Office of Admissions? (Cal)

So I know the whole lecture on senioritis and keeping up my grades and all that. Regardless, here is my situation.
My first semester, I got 3 B’s in an AP class and one C in an honors class (as well as getting an A in an online class). UW, those classes make a 2.75 GPA, but I did only get one C so I’m wondering if I should just pull my grades up next semester and try not to worry about it. Weighted my GPA is a 3.25, and I did also take an online class so I’m wondering if that could help out my situation. Any advice before I send in my ITR?

It can’t hurt to call.

Not sure where you got in - or if you’ve submitted your intent to register - but, the ‘conditional admission’ at most colleges spells out what’s expected from you. Read what they told you.
