I go to UC Berkeley, which seems to be on par with the top schools for mathematics. Right now, though, I'm just in the math student union and taking general undergraduate classes, something that can be done at any university. Now I'm not trying to attack or say other schools are worse; in fact, I'm feeling that, besides the words on a piece of paper, I'm struggling to see the benefit of Berkeley over any other school for math.
For those of you who are past your undergraduate, what advice do you have for me, and could be for more general students at the "top" schools? How else can I take advantage of the wonderful opportunity I've been given to study math here? What would you wish someone in my shoes would do? Is there a certain professor who is extremely renowned whom I should get to know? Any smaller institutes or departments under math that Berkeley does best?
Again the point of this isn't to make others feel bad. I just really want to make sure I don't graduate and realize I was sitting on an amazing opportunity and didn't take advantage of it when I could have.
