I am not giving up hope just yet. Their email address has been unresponsive since before the application deadline, and it seems like the merit fellowship recipients have been admitted first. It may be possible that although the fellowships have been awarded, some seats (without merit grants) are still under review.
Though considering it is Berkeley, statistically it's much more likely than not that an applicant will be rejected. Does anyone have backups they're happy about? I'll be accepting UCSD's M.Eng in BioE offer if this doesn't go through.
