I'm a lurker here but since I got almost the exact score (206) I thought I would comment. My downfall was probably that I didn't take any practice tests in the duration of my study except NBME 15 seven days and UWSA 1 four days before my exam (since I had the mentality that I should get through all of UW first and then start focusing on weaknesses). I scored 203 on NBME 15, got a 224 on UWSA1, and then did a focused run through FA + some questions for the last 3.5 days.
I finished UW with an average of 51%, which predicted me at 200ish. I was hoping/praying that UWSA would be more accurate on the actual thing, since I've heard good things about taking UWSA1 right before the exam, but it was hard because I had so few data points to go off on. Maybe the fact that UWSA overpredicts by 20 points is actually true... And NBME was almost spot on.
I attend a Top 15 med school too, so this kind of score is embarrassing compared to how well my classmates do. I must admit that I really did coast through the first two years and ended up passing in the lower half for pretty much all of the courses. When I started UW on random timed, I literally was scoring ~35 percent per section, and then I gradually brought that up to about 63-67% per section at the very end. In retrospect, I felt I came pretty far, but I probably was just learning what I should have learned in the last two years during the exam prep period.
If I could give advice (if I'm even in a position to, lol!) is that don't undervalue your physical classes during the first two years. I felt going through FA helped me a lot (I could "see" pages in my mind when I took the exam), but as a whole I felt too shaky about my ability to "integrate" different facts into the clinical vignette at the end and I'm sure this is what really hurt me. This is something that one can learn during the designated exam prep period if one is dedicated, but it was something practically given out for free during the classes in the first two years. You probably wonder why I didn't take NBMEs but a lot of my classmates really just took 3 weeks, went through UW and FA, went and took the test, and got 230+. I gave myself 6 weeks and I thought I could do the same (I'd be ecstatic with a 230 since I only want to do IM), but I probably at too weak of a starting point to begin with, unfortunately. The exam is really not a big memorization exam - the ability to reason and not be misled by the distractors is far more of an asset than a simple strong memory/ability to regurgitate facts.
Also, I must say that the stems on the actual exam now are REALLY LONG. I usually finish UW timed sections with 10-15 minutes to spare (same for the UWSA), but I was rushing on almost every single section of the exam, with barely 3-4 minutes in most sections, which I spent going over the ones that I was just purely guessing on/choosing between 3+ choices. I'm sure this hurt my confidence/accuracy significantly, and something I could have prevented if I took NBMEs earlier/more frequently.
Ah well, typing this up was somewhat cathartic, determined to do well now on clerkships and spend this year seriously studying for CK. I *think* I have what it takes, I really just need to come to terms with my weaknesses, and buckle down and do it. And this is a perfect (negative) case of how MCAT doesn't correlate with your Boards score - I got 36+
