I can see why you’d be fearful about Williams -
But this is like picking between Tom Brady at QB…and whoever will replace him this year.
They may be fine and Berkeley is - but Williams is at a level so beyond anything you can imagine.
You can and will get global exposure there, you will be supported/funded into internships, etc.
Your con on Williams #3 is so ridiculously wrong - it’s a pro pro pro.
Also - #4 - so I was checking different schools for my daughter because her trip was cancelled (not enough kids) and we were signing her up for a trip at CWRU (also cancelled - prof visa issue) so I looked at the UC site and they had tons of cancels. So don’t think that what you see is what’s actually happening. Semesters abroad yes - but one off trips not necessarily.
This is like shopping at Nordstrom vs. Wal Mart…for real.
UCB is obviously a great name but - you are talking about the elite of the elite - and it would be crazy not to try (in my opinion)…not to mention, in the end, do you want small and supported or to be a part of a big bureacracy?
If you want a global career, you’ll need to learn to take chances…and that starts with being away from home for 15 or 17 weeks.
Good luck.
