Some of these assumptions may be incorrect, but here goes.
EECS admissions is anywhere from 3% to 5%. L&S overall Admissions is somewhere between 15-20%. So that’s roughly 4x to 5x. I’m not sure if L&S breaks down admits by intent majors, but even if it did, surely there are going to be say a French or Philosophy major who invariably tries out for CS - because he or she can.
I think that the 3.3 GPA in actuality weeds out a lot of intent candidates, but I doubt if that barrier really prevents people from trying. Who really is going to get scared off by a 3.3 GPA? After all, almost everyone going in is pretty smart via the fact that they got into UCB in the first place, plus a show of hands at the Pimental presentation showed that virtually 100% of the students had already had computer coursework at the HS level.
What might scare off people is if the university would publish stats as to the percentage of intents who wind up not making the cutoff and/or change intent majors along the way. You can make an educated guess based on the Berkeleytime stats for the 3 weeder classes I suppose. I know for sure that CS Advising always tells the kids to be flexible and to be mindful of their classes just in case they need to switch majors.
