The average CS starting salary for Berkeley grads is around $110K, possibly more now, but some of that is due to housing being so expensive around here. I personally think that the Maryland CS program is an outstanding program, a couple of my neighbors have their kids going there for CS. $140K diff overall over 4 years is a lot of moolah.
Are you in L&S CS or EECS for Berkeley, and are you direct admit for Maryland for CS?
