Housing at Berkeley is in a much better situation than even one year ago. It is anticipated that anyone who is a current freshman who wants school-sponsored housing should be able to get an offer for next year.
There are some courses that gets filled up really quickly, but then again a large public like Berkeley will have so many more classes available than any private. A lot of the lower division CS classes will usually expand such that everyone gets in off of the waitlist. Now that poses a different type of issue, one of overcrowding, but that’s another issue for another day.
