Maybe this is a no brainer but I figured I'd ask... I've heard both sides from many different people...some say universities encourage undergrad students to apply elsewhere for grad school, thus if you are going to say, UC Berkeley like me and apply there for grad school as well, it will be harder for you to get in than it would be for a student applying from a different school. Other people say this isn't true and there is no bias against students re-applying admissions wise. I can see the obvious benefits of going elsewhere for grad shool (gaining experience in a different enviroment, working with different professors, etc.) and I know that this is most definitely the norm for physics students, but I was just thinking...it is Berkeley. I mean why not stay. I love it here and it's arguably the best public university in the USA. I have other reasons to stay as well...friends, family, a great girlfriend, I love the bay area...the school just feels like home. I know I've got to leave the birds nest eventually but if I could get 5-6 extra years out of going to Berkeley that would be pretty awesome.
