There are tons of posts already on this. Read stuff I have posted along with Pitman and a few others that actually attend or have attended. The 12:1 is wrong even in first year. First year you don't do clinical visits, you do clinical coaching (which is the same group as your CBL group) and CBL. The biggest CBL groups are 10 people (mine this year and last year was 9). Second year, they split the CBL group in half for clinical coaching visits - which are done in hospital where you see patients. The misinformation is rampant, which I don't quite understand. I have said it before, there are tons of legitimate things to complain about just like any medical school, but some of the stuff I see people write is just completely false. Class size is ~500, but they break up all of the non-lecture stuff into smaller groups of 50 or so. You don't have to attend lecture if you don't want to. 95% of them are recorded and/or have slides posted.
