I will be a chief resident next year and actually got the idea from my PD of delaying my ABIM exam until next summer as they had informed me that they did not require it for the chief year. The only reason I am even considering this is that my wife and I are expecting twins this summer and less so, I have a few research projects I was really hoping I could wrap up by the end of my PGY3 year. If I'd be able to space it out until next year this would obviously be less stressful. However, I am just worried now if this will in any way look bad on the interview trail for fellowship. Wondering if anyone has any experience or input on this?
