Do you think they don’t know where each applicant is from?
The UC system has already acknowledged they have benchmarks for how many out of state residents they aim to have in each class. It’s only recently begun to face pressures to revere the trend in favor of more residents at the undergraduate level.
Audits have been done in the past that found they have lower admissions standards for out of state residents and the rational is that the out of state resident tuition helps subsidize the in state resident tuition.
This is pretty well documented at this point, it’s not a conspiracy theory. The universities are businesses after all is said and done. That includes the dental school.
For the op - like I said, every program in CA accepts out of state residents. The % of the class that’s out of state varies per institution but if you have the stats to get into the program, you have a shot.
