How often do UCs update their min. GPA requirement for TAG?

For TAGing a UC, how often do schools update their minimum GPA requirement? I am probably going to TAG UCI, but they have one of the highest minimum GPAs for tag(3.4). I have a 3.5 right now, but if I don’t get my projected grades this semester I’ll be lowered to a 3.42. I am nervous that they will bump it to 3.5 for fall 2017 admission. But 3.4 is already pretty high.
