@Anna2014 your son is highly, highly qualified and deserves to have a spot in Berkeley and UCLA. But beware that, like many well-qualified applicants, your son may not get the spot. Now that is not at all your fault. That is just the nature of the admission process, that they have very limited spots available each year.
If your son gets in, congrats, he may even be my roommate next academic year. But even if he doesn’t get in, remember that colleges don’t determine his life forever. Make UCLA or Berkeley regret for not having accepted him when they had their chance! There are many Nobel prize winners, Fields medalists, and many admirable people who attended provincial colleges, and some didn’t even finish college (like Steve Jobs). If he believes in himself, that he can do anything he sets his mind to, he will have a bright future.
