Question Regarding UC TAG

So my next semester will be my last at a CC and I just need to take 3 classes to get to 90 quarter units for UC Davis (I’m taking 2 prereq classes and an oral communication class for CSUs)

My question is if I submit my Tag to Davis saying I’m going to take just those 3 classes will my Tag be voided if I decide to take another class or 2 for more transferable units? Or am I good because I will be completing the classes I outlined in my Tag with just an added class. I’m saying this because I don’t know if my schedule will allow me to take 4/5 classes next semester so I’m just going with the safe 3 classes to get me to 90 units.

I would post your questions in this thread: http://talk.collegeconfidential.com/uc-transfers/
