I'm so proud of you! Now, who gives a care what anybody else did? Really! You've got the rest of your life to learn it better (the human body). I remember a dr. telling me one-time, that he'd thought having to be elbow-deep & digging in/through the bodies like that, so early in the game (of med school) was a bit "pointless," for him - anyway - as he didn't yet understand what it is he was (really) looking for. In other words, he'd felt they'd benefit greatly / or even more-so, if this was done either later on, or doubled-back around again, and revisited, or re-freshed, as it were... once you knew what the heck it was you were looking for. So, in summary, he'd said to or told me, that he didn't get much (use) out of them just then.

You can always get better, and as these things come back around again & again, I'm sure at some point some certain things will solidify more & then, you'll be feeling much more confident, capable, and credible/or as in competent, or sure-of-yourself; & your skills. Which, by the sounds of it, went miraculously fine - anyway! And so, I'd or I've always felt that, w/things like these. . . You either know (or knew) them--or you don't. And there wasn't much in between. No faking, in other words~

Good work. Keep it up!
