I don’t know about UCB - there are other UC experts on here. Based on what you said a 4.5 and the chart above, seems like you do.
Gtwon - sure, why not - you have a chance. Worst case you’ll get deferred to RD. Your ECs line up well with the major.
I would say - you need to define your activities well - that’s really it - example don’t say you’re a VP @ tedex - but what do you do, etc. For research on youth homelessness - what are you accomplishing, etc. You’ll have little space but.
Make sure you are being honest - because what you are showing and i’m not doubting you, but it seems near impossible.
Good luck.
