Undeclared to Computer Science?

I was accepted into UCI as Undeclared in the Department of Undergraduate Education even though I chose Computer Science as my major when I applied. If I choose to go to UCI, what are the chances of being able to change my major to Computer Science later on?

I am in the same situation. Luckily though I was also accepted to UCD and Cal Poly SLO. If it is difficult to declare as CS at UCI that will definitely affect my decision process.

This may help.

Also, although I am not familiar with the UC system, I think like in most universities the first 2-4 semesters at UCI will consist of general requirement courses.

Nevertheless, it does not hurt to be well informed before making a decision.
