Absolutely yes. I have to keep studying for the COMLEX and every time I go into first aid it feels like I find something else I got wrong. I'm keeping a running list of things I'm pretty sure I missed. Its actually helped me stop thinking about them believe it or not. The bad thing is I'm up to like 35 things 😢 (really embarassing, but it is what it is). At least 10-15 of those were free points that everyone else probably got, and 99 out of 100 times I would have too. I was just too stressed/tired/rushed. Time was never an issue until I took that test.
Came in hoping for a 230+. With that many known misses, and countless more that I don't remember, I would be ecstatic to receive a 210.
Extremely frustrating to know I could have performed much better, even more frustrating that I honestly think I may have failed the biggest test of my life. I know everyone feels that way, but with my current score going down and down, I really can't shake the feeling.
So yeah, if anyone out there feels unsure of their performance after the USMLE, you are not alone at all.
