Hi - totally appreciate your thoughts since I as a mother have been having the same worries! As I mentioned in another reply, his ONLY reason for considering the CCC route is personal/ family related, has nothing to do with UCD not being “good enough” or holding out for UCB.
Thank you for highlighting the risks - I will share this info so that he can make a fully informed and balanced decision. UCD is a great option and he should be ready to accept not-as-great options if he risks the CCC route - eg maybe goes to a CSU instead of a UC. Who knows
