False confidence??

Has anyone ever felt good coming out of the real deal and actually preformed well? I walked out feeling great, aside from one passage in my RC (LR LR LR RC). This is my second attempt, granted the last one was over a year ago, and I felt exponentially more confident in my performance. I just feel like I could’ve been overly confident throughout the test considering my first LR was super easy. Or, just maybe, I’m a chronic overthinker! Any positive experiences with this?
