These above experiences and JDUB's statement speak to a few important aspects of how the test is evolving that people starting studying up to taking the test soon should understand :
1. EVERYONE'S TEST IS DIFFERENT. Just because there are multiple posts on SDN about crazy biochemistry one week does not mean your test the next week will be the same. Do not waste time going crazy with every biochem resource you can find. If you read that and it makes you question your competency on biochem, brush up from FA/UWorld. My test was full of micro, whereas the weeks leading up people were constantly coming back from tests full of anatomy. Mine had moderate amounts of manageable anatomy. Which brings me to my next point:
2. You cannot predict the crazy things they throw at you. This has been beat into the ground ad nauseam on this site but people still ask how to prepare for the WTF questions. You can, however, help yourself by learning the information well and from different angles. I can't tell you the number of times on my test I was stuck scratching my head on something that seemed ridiculous only to break it down to the basics to determine the (straightforward) answer. Were there things I didn't know? Absolutely. Could I have prepared for them? No. Sometimes you get stupid things your remember from basic science years, sometimes you are just unlucky.
3. Learn how to take the test. Learn the basics, then learn how to answer questions. Keep pounding in the basics from different angles. Repeat. This ties into #2. More questions=more experience with weird presentations=better prepared for WTF questions=higher score.
4. Above all else, JDUB hit the nail on the head IMO. At some point, you just need to stop and take the test. 2 days before the test I felt like I knew nothing. When I sat down and entered the tutorial I realized I forgot to review some of the equations the day before for renal. And you know what? I had a question that was exactly what I had forgotten to review, and got it right from questions and experience. Not by spending more time studying. People spend a year of studying memorizing minutae to get 2 or 3 more questions right but they miss 10 from burnout/missing out on question experience by using too many resources and thinking they need to learn more. Questions, questions, questions.
Lastly, this test is doable. It sucks, but IS doable. You are all smart enough to do well. Spend your time wisely learning how to take the test and the material from proven resources. For the M1s reading this, learn it right the first time. Don't waste time with FA first year. Find something that helps your long term memory maybe, but put time into 1st and 2nd year. Start a little before or during Winter break M2 and slowly build up. It makes things so much easier. And above all else, don't torture yourself by spending expansive amounts of time studying obscure facts on a topic you read on SDN. When your practice scores are where you want them to be, you're doing something right. Trust your instinct and your prep. Good luck to everyone-stay confident and you'll kill it.
