I felt unsure of my test performance while walking out of the real deal - It wasn't a new feeling at all, as I felt the same with each practice test and they all turned out fine. I told myself I wouldn't look up any questions after the test and I'm glad that I didn't. I just received my score a couple days ago, so I thought I'd contribute.

I was super relieved that I was able to improve on my practice test scores, I felt like the actual test wasn't as bad as I was expecting, but it was difficult. I had a lot more flagged questions as usual, but I wanted to make sure to revisit any question I was unsure of. In the end, I think I only ended up changing 3 answers.
During my dedicated study time, I made 3 passes through FA, 2 passes through Pathoma video lectures, 2 passes through Sketchy, and about 5 passes through Lange Pharm cards.
I used Uworld throughout 2nd year, so I was able to finish it before I started my dedicated study (ended with 71%). Got through over 1000 Kaplan questions (78%) before I started Uworld for the 2nd time during dedicated study (finished at 89%).
