Just wanted to say thank you to everyone that has posted - it made waiting for scores a little easier.

Resources that I used: Pathoma, FA, UW (only finished 40%)
Some quick/general things:
Start studying early, getting familiar with and incorporating resources like FA/UW/Pathoma into your 2nd year will really help you. I regret not doing this. Our school didn't
"teach to step" (...they do now) ....most 3rd/4th years advised us against starting early (I still don't have any idea why, maybe everything is easier in hindsight? who knows).
Everything you need to know is in FA... but you need true understanding to remember it or make any use of it (this comes from the foundation built in the first 2 years). This
"foundational understanding" is strengthened by Pathoma and UW explanations (and other HY explanative resources like BRS phys/firecracker/etc. (i didn't have time to use these.... really wish I did)).
The explanations for UW are AMAZING! Definitely wish I would have finished UW and gone over it a 2nd time. I didn't have the attention span to spend 15 hours a day reading and differentiating each answer choice. I do think that my score would have been higher had I done this (see next).
Step is much more of a thinking test than I expected it to be. Unlike UW, they don't try to trick you. Also, In UW, I just never knew what they were talking about. Step was more like "oh i know this!" ...but then the
"classical" answer choices weren't there and I was left to make a
"best guess" (I marked 10-15 per section on average).
I'll close by saying a little bit about my personal experience with
burnout (which i never thought could/would happen to me). We had 1 month of exams and then ~1 month off before step to study. As you can see from my scores, that last month didn't do **** for me.
If you're a
"crammer" (like i am), fight the urge to procrastinate on studying/doing qbanks. At some point I felt like I could muster up the motivation to
"power through" UW or review pharm, go through goljan HY again, etc... I made a
"schedule" everyday, it was always doable in the sense that if i could convince myself to do anything, i could have probably done it. I can't count how many times I remade that schedule because I didn't finish. In hindsight, I probably should have taken a few days off but I couldn't convince myself to "waste a day" and basically wasted the month.
I am more than happy with my score but I do wish I spared myself the month of consistently stressing myself out for no real gain or benefit.
Post-step: thought I failed. legit failed. The only thing that wasn't a blur from that day was the easy 1 line factoid questions I couldn't remember, the ones I didn't even mark. For everyone that is still waiting,
TRUST YOUR AVERAGES!!!
