I just got accepted to UCSB, but I’m not sure when I will receive the admission package. Does anyone have any ideas?
Also, if I got into there, does that mean I have a decent chance of getting into UCLA, UCI, or Berkeley?
Thank you! 
There is a significant difference between what it takes to be admitted into UCSB and the likes of Berkeley, if you barely scraped an acceptance from UCSB maybe not, if you were comfortably admitted then maybe, but nobody can ever say for sure, it is up to the admissions officers and what they see in your app.
