is it possible to transfer from a csu to a uc

<p>I am most likely going to cal poly pomona but my first choice was uc irvine or ucla but i got rejected. My major is computer science which is very competitive. and i wanted to know if i have the chance to transfer from cal poly pomona to uc irvine or ucla after either my first year or my second year? i've read that it is nearly impossible to transfer from a csu to a uc. so i wanted to know this so i can know if its better to go to a california community college to then transfer to uc irvine or ucla. and also i wanted to know if cal poly pomona is better at computer science than uc irvine and ucla since cal poly is a polytechnical school?</p>
