I know at the end of my PGY1, I didn't think I was prepared until I precepted a student and realized how much I actually learned in residency compared to what was taught in school. Learning may be occurring, but I think as residents we get caught up in just plowing through each day. And as one of my preceptors once said, there will be things you don't know once you graduate from residency - if you think you know everything, you're overconfident.
And if all of this is not the case, I agree with talking to your RPD to discuss how you can make the most of the last 2 months so that you will be prepared for whatever you want to do.
