Taking major prereqs in last semester before transferring to UCB/UCLA. WIll it decrease my chances?

I know that it has been said that it really does not matter whether you don’t finish your prereqs during the last semester before transferring. However, I am just curious if it will decrease my application.

I intend to transfer UCB Bio for Fall 2018 and I plan to take my last Gen Bio 2 class during my last semester. Will that affect my standing? I heard that TAUs only update Fall’s grades. I was wondering if my last semester will hurt my application in the process.

Nope. Nada. You’re fine.
