By and large, it seems that med students don't get much exposure to different specialties until 3rd and 4th year. However, if I settled on a trying for a competitive specialty like radiology or ortho during my third year, wouldn't it already be too late? How would I fit in the research that seems to almost be required for these sought after residencies? If I try to cover my bases and do some ortho-related research during the summer between m1 and m2, and later decide to go for an ENT residency, am I screwed?
