I too am a graduate of UCLA and I must say that I agree completely with what chocobo is saying. I wouldn't base too much of the decision on what the third year students are saying. Its funny, when I was a third year, there were quite a bit of gunners who were on track to finish early, and they used to brag about it. I, on the other hand was pretty behind compared to my classmates, with research, externships, etc, etc. The greatest irony was that I was one of the earlier ones to finish requirements (and this was with around 2 weeks left to graduation) and those that used to brag as 3rd years finished later than me. Its also true that around 15-20 didn't graduate in spring, but I know the departments cleared them as they finished, meaning if you finished 2nd week of summer, they signed you off to leave.
Anyway, the point is, lot of things go wrong during dental school to set you back and yes, ucla requirements are horrendous and patient pool is not great. I hate many of the faculty there. I'll probably never donate a single dime there. But will I attend UCLA again? Absolutely. You can't beat the price, nor the location. I have to say that UCLA is probably in top 5 in terms of difficulty in getting in. I've interacted with dental students at my residency and they simply are not at par with UCLA students. I am not sure if the reason is due to the education or the fact that to get into UCLA, you have to be pretty smart. In terms of specialty, 10 of 10 omfs, 14 ortho, 5-6 perio, 3-4 endo, and 2 prosth. So i guess that makes around 35% specializing.
So to the OP, i doubt that you got into both programs this early on, since acceptances aren't handed out till december, but if you are fortunate to get into UCLA, then by all means you owe it to yourself to go there.
