UCSD Student Life

Hi! I am from India and got accepted into UC San Diego (Revelle College) for CS major. I was wondering where can I contact current UCSD students to get to know more about social life, dorms situation, internship possibilities, competitiveness level in the CS program and the classes offered. Also, if one could provide more insight as to UCSD or Calpoly SLO would be a better choice for CS major.

Have you looked at the website? That would be the first place to start.
It took me all of 2 seconds to find the Student Life section.

You can also look for the Facebook group of admitted students.
Google is your friend.
