Withdraw to go to CAL State

I’m currently in my first year of college, I applied to nursing program but I got rejected so I went in as a UU major. My plan was to just re apply to the nursing program my 2nd year of college, but I grades are looking horrible and I know that there is no way I will get into UCI’s nursing school. I want to go to a cal state ,maybe Fullerton or long beach, to do nursing. But my concern is that I will most likely fail my general Chem1A and Bio93 class. So can I withdraw from UCI before any grades become official and apply to a cal state as a senior from high school?
