Do prereqs have to be done before application or when you actually go to the university?

I’m currently In Chem 1 & Calculus 1. I need to finish Chem 3 and Cal 3 before I transfer. If I apply in the fall I would be doing Cal 2 and Chem 2 while applying to Uc berk and UCLA. Do the UC’s look at that spring sem where I would be able to do Cal 3 and chem 3? Would they take the classes of spring 2019 into consideration for my fall 2018 app? Pls Help! Thanks!
