Applying as Undecided Major?

<p>Will it be better for me to apply as undecided for my UC apps. I was thinking of applying as a Computer Science and Engineering major but i'm not 100% sure that i would want to go under that major. Plus i don't know if this is true, correct me if i'm wrong, if i apply to a certain major that is famous for that school, my chances of getting in would become lower. Again, I might be wrong. </p>

<p>I'm applying to:
UC Davis
Santa Barbara
Irvine
Santa Cruz
Riverside</p>
