Here is a good horror story (not to scare you, as I only seen this at this school, and I have seen the process at 4 now).
I used to work in a lab at SDSU (2003) where one of the chairs of the PhD clinical SDSU/UCSD program would meet to go over candidates with other members. I was privy to their discussions and basically, they were all carrying around this piece of paper with about 25 names on it then said the following in columns: GPA, GRE VQA, name. All the way down it was 4.0, 800, 700, 800, etc. It was so ridiculous. Can that many people score 800 on these tests?
