Ehhhhhh -
Law - you could go from either major equally. Nursing, might in fact, offer a diversity that they see less of and would appeal to them.
Business - going into a decent b school - you’ll need work experience - which you’d get from either degree - but nursing more easily.
Maybe a PhD in psych - but I think it’s an overstatement in general. I don’t believe the OP is losing anything at SDSU - except a UCLA experience (whatever it entails) as opposed to an SDSU one (whatever that entails).
