SLO is the only CSU that uses 9-11th grades. The rest of the CSU’s use 10-11th grades so hopefully you will apply to several other CSU’s that have good Business Admin programs such as CSU Fullerton, Long Beach, San Jose State, San Diego State to name a few.
All you can do is apply and see what happens. Have you checked the MCA scores for Business admin admits from this year? How do you compare/
