i'm going to disagree with all the above. first off, i took it at the end of february and it was not horrible at all. I was not on an orthopaedic rotation or working on applications/interviews like I would have been earlier in the year. Because of this i was able to study for almost two weeks and just take the thing during a period where my schedule was very light.
Secondly, of all the things on your app, board scores are the least interesting and important in the long run and i dont think that is going to change. Sure, it helps to have a score >230 and if you dont it is probably *helpful* to take step II early. that said i dont think it is essential because if you have good research, grades, LoR, extra-curriculars then boards become increasingly less important. If you are in a possition where your step one is not great or your app is light on other things, of course you will want to take it early. If you did better than 230, an impressive step II is not going to be the make-or-break item on your app, now or in the future. you are better served spending the early part of your M4 year doing research or other extracurriculars to set yourself apart.
The first response on this thread was the most accurate. you need to look at your own app as a whole and put your board score in perspective based on that information. You also have to be honest with yourself about how important it is to get interviews at the HSS's and Pitts of the ortho world. The dirty little secret that is seldom emphasized on this website is that they are like all the other programs out there--great at some things, not as great at others, and certainly not the ideal program for every budding orthopod out there.
