a couple of my high school chums transfered to UCLA a year ago. they managed to get that priority transfer program, they feel that its a totally different ball game as thier 4.0's evaporated. and unfortunately i have to tutor them (and im not exactly the brightest guy)
i took a couple of GE and physiology courses at CC and i found them to much more managable then univeristy courses but i will not say they are full of college rejects, though plenty of them are (like my other chums who decided CC should take 3-4 years).
as far as those that party all day, they are still the tops of thier high school and take grades very seriously. nobody "never studies" because they will get a zero everytime. work hard party hard! partial credit are hard to come by and failing is very easy.
and the curve is brought down not because people dont study, but because the test ist damn hard. everyone in the class knows all the material, that is a given, the teacher knows that so they throw curve balls, page after page, once in a while we get a freebie like "explain theory x" or "derive this forumula" (but even those are tricky because we try to find the trick to that problem, existent or not, because we are not use to getting freebies!"
then again, a good friend of mine transfered to berkeley are from what i heard is setting the curve in each classs... also, many people i study with are transfers and they are some of the smartest people i know
there is antecdotal evidence supporting each side, but in the end, its th Opt schools decision to weigh each institution and since they weigh university more, we will just have to live with it
