I agree and disagree with what's been posted above. For my ortho rotations, i thought the above were applicable and hard work and "fitting in" were crucial.
For medicine, ob/gyn, peds and family, i found that kissing rear end was the way to go. Pucker up and kiss as much rear end as you can stand without vomiting at the end of the day. But you still have to kill the end of rotation exam to get honors so study hard too. But remember that a large part of your grade is subjective (i.e. predicated on butt-smooching)
For surgery, i felt lost in the crowd. Too busy, not enough time to kiss rear end as efficiently as other rotations. But conferences are a great time to kiss deriere (i.e. ask questions when you could care less what the answer is).
In sum, be yourself on your ortho rotations cause orthopods in general are pretty cool and don't like it when you kiss rear end. I think it reminds them of med school years and the kids who wanted to do medicine and they get turned off. But for the others, an opportunity to kiss rear end is an opportunity to shine, and vice versa.
And one more piece of advice from someone who's "been there": There are 2 types of butt-kissers in medschool - the "nerdy" butt-kissers and the "cheesy" butt-kissers. I suggest you take the former approach because it p@#$es off your classmates a little less than the latter. Cheese is not good. Donuts and coffee for residents is not good. Yelling "Good morning everyone!!" with a big grin on your face at 6 a.m. to the nurses at the station in your short little white coat is NOT good. But bringing in articles on relevant topics and bringing it up in rounds or conferences is much better. Hold off on the cheese as much as you can. If you don't have a patient, don't say "I wish I had a patient to present!!" during rounds. During morning report in medicine, don't cross your legs and lean forward with your coffee and nod and smile at everything your resident utters. That's cheese.
