oh ya definitely like 10:1 - strangely enough though it has been enough on things like shelfs and clerkship tests to perform at the standard i was 1st-2nd year (was always one to try my hardest to do as well as possible)....i think as u advance in your schooling you don't require the 12+ hours anymore, as alot of this stuff you DID learn 2nd year and this is a repeat, and definitely you are learning stuff on the job - i don't know, but it does seem to work. i loved the life of a 2nd year, sleeping in, studying comfortably for 12 hours a day and always thought i would prefer it to third year - - until i do try to study and am DONE after like 2-3 hours and see underclassmen there all day like we used to be.
