Can I change my major after I transfer to a CSU?

Hello. I am planning on transferring to a CSU for the Fall 2016 semester from my community college. Preferably Chico or Fullerton. My problem is that I applied as a Biology major. I realized after the Fall 2015 semester that Biology is not the right major for me. I have been wanting to change my major to Accounting. Right now I’m taking some classes for the Accounting major. Will it be hard to change my major once I get there?

Yes, But it may take you longer to graduate since you’ll need to take more classes for accounting
