Pick the track that works you the least. Ask around. You learn very little during the rotations that will help you on the shelfs and most importantly, on CK. I am at a track that REALLY works the students hard. For example, in Surgery I had to work 19 straight days without a break. I'd be at the hospital at 5 am an get home at 7 pm exhausted. It's very tough to pick up a book and read and then do U world questions. My shelf scores suffered for it. Now I'm dead scared about to start studying for CK. I have a lot of gaps in my knowledge.
Of course, the flip side is I will be a better resident. I wrote a ton of notes. I learned how to act like a resident. But I have to get into residency first. I know people in easier tracks (hint: in the South Eastern US) that got out by noon everyday and just studied for shelfs and CK all day and got awesome shelf scores. They feel pretty confident about CK, which is all that really matters for us. You could've gotten all A's in rotations, but if you bomb CK its lights out.
