SFSU college business school requirement

Hello guys,
I’m an out of state transfer student, just wondering if there is any pre-major classes in order to be admitted in the business school? Or is it directly admitted when I also received acceptance from the university division?
If I have to take pre major classes, how long will it be? 1 semester?
I just want to make sure that I can graduate in 2 years.
P.s. Currently in upper level division
