Hi,
I'm a first-year at Keck so I can provide a bit of insight. We are stricly pass/fail (ie 70%=P, P=MD, none of this high honors/honors bs), and are not ranked against one another. The only score that is ever recorded is our cumulative exam and that is for Dean's recognition and AOA. Other than that, everyone is EXTREMELY collaborative and we get e-mails almost weekly from upper-classmen handing down study guides, notes, tips, flashcards, etc.
LA is definitely crowded, and USC is not in the best area. On the flip-side, we have a BRAND new hospital (we just moved in November) that serves a huge, extremely diverse population. We start interviewing patients (in the hospital) in our second week (of first year!), and start physical exams in January of our first year. As someone mentioned above, cases of TB (I've seen one already) and other random illnesses are common. Unfortunately for the patients, but fortunately for us, we see a lot of patients whose illnesses have progressed beyond the point most other students/physicians will ever see (due to lack of health insurance, large immigrant popn, etc).
Don't worry about the area though, because we have a very secure campus with tons of security guards. Alhambra is flanked by a lot of nice areas (like Pasadena) that are very nice and not very far, so most students choose to live there.
The curriculum is amazing...very clinically oriented (I guess it has to be since we see patients so soon) and in the 'system' or 'block' format (ie you learn everything about heme, then musculoskeletal, skin, repro, etc). Since we are a private school, we are pretty spoiled and get pretty much whatever we want (we just talked our dean into putting in a new flat screen with sattelite, new couches, new pool table, etc in our lounge). Plus the USC football games don't hurt.
Oh, and our board scores are in the top 3 in the country and our 4th-years are far more competent than most interns/early residents (probably because they already have their 'own' patients at this point). We are not only affiliated with LAC+USC, but also with Norris Cancer Hospital, University Hospital (ie where the rich people go), and many of our clinical instructors are affiliated with other hospitals in LA.
Financial aid and scholarships are available (I got one) but yeah, the school is pretty pricey. However, unless you are going somewhere in-state, it's on par with everywhere else.
Ok, so that's my plug. I absolutely love Keck, so lemme know if I can answer any of your questions.
