Apparently you think like, or your mind is "wired," similarly to the EK authors. Just as when people "talk past" each other, or fail to see what another person is trying to explain at first, sometimes VR passages AND answer keys, completely overlook an entirely valid perspective. This has been noticed not only by myself, but by many tutors, professors, etc. AAMC has very few, if any, passages and questions like this, but EK and other (non-AAMC) test prep companies usually have some.
In order to IMPROVE, you will need to inquire about why you got questions wrong. The best method for that, if you can afford it, is to run those questions by another person. You can also look it over yourself, but in all likelihood, there will be scenarios where you understand YOUR reasoning, but will have extreme difficulty FINDING the authors, unless the answer key was sufficient or what some people refer to as an honest error (ex. misreading) or silly mistake (ex. circling the wrong answer even though you knew the correct answer).
It's also important to make sure that wishful thinking doesn't rule. An example of wishful thinking, is when someone reads on answer key and both their original reasoning AND the answer key's reasoning make sense. Then, you need to figure out HOW you could have got the question right while being aware of both your logic AND the test maker's logic. WHY is the test maker's logic deemed "better?" Wishful thinking is when students give the test maker a free pass, and fail to resolve that issue.
Some non-AAMC questions are, "duds." It is also important to know when to "leave well enough alone." IMO, you definitely want to know WHY you got MOST of your wrong answers wrong, but if you cannot figure out a small handful of questions after running them by a few different people who got 12's or better on VR, feel free to forget about those non-AAMC questions. They are probably "duds." It is just not worth your while to keep pursuing them, after so many hours. (You can still keep a list of them in case you find a new person to run them by. Just don't be too concerned after some point.)
The ONLY other reason, I would stop checking answers or stop looking for the correct answer would be if I were battling test anxiety.
Hope you've found this helpful.
Good luck!
