Do I need to complete math the fall before transferring?

I plan on transferring to a uc the fall of 2019. I have already completed business calc and the only other math I need is stats 1. Would I need to complete it before the end of fall or can I take it during the winter or spring? I heard somewhere where you have to complete your math the fall semester before you transfer, is this correct. I am majoring in BioPsych and I want to TAG UCSB
