Congrats on passing!!
I would debate the idea that "you will get credit for the second best answer". That is not true. What the NCLEX DOES do, is narrow you down to a competency where you have a 50% chance of guessing correctly (as opposed to guessing 25% correctly, which would obviously be random, and anyone taking the test would have a 25% chance of guessing any given question correctly). In other words: can you rule out 2 questions successfully most of the time? There will almost always be 2 easy rule-outs on any nursing school
or NCLEX exam (i.e. you can easily rule out an assessment-type response if it asks you what INTERVENTION you would take). Even if you are successful at ruling out the obvious two "no-ways", you still need to guess or, better yet, KNOW the answer to the question out of the 2 responses left, MORE than 50% of the time. So while your strategy is not a BAD strategy for questions where you don't have a clue and must USE a strategy, the test is still going to narrow you down to a competency, and if you're above their line you pass, below it you fail. I think it's slightly irresponsible to suggest that people will pass the test if they narrow it down to 2 answers and go with either one. This test is also about critical thinking, and in many cases you should be able to narrow down the answer to the absolute correct one.
