it was just my overall experience, from the ppl i talked with.
for example, when i asked how is the retention rate, they will say the best instead of giving me exact numbers. When asked about board scores , again its "the best" without specifics. they really made it seem like ucb was the best opt school and while it may be true, the reasons they gave were ridiculous, like we have nobel lauretes, but they fail to mention they dont even teach at the optometry school. All the schools i talked to said that all the schools give you a good education while berkeley says they and only they can give you the "best education at a world renowned university" again this might be true but they struck me as "its all us" attitude that really got to me. And my personal favorite was "so what school is your backup" they assume that everyone wants to go to berk as their first choice and never thought ppl could apply to them as the backup school!
its my experience and im just sharing them, if you have a positive one please share! take my ramblings with a grain of salt, afterall im just another poster online!
