I'm currently in this grad class, but I have serious doubts I have enough time on my hands from my busy schedule to do well in this class. As a result, I'm considering to just audit the course, which in my university means: "to go to the class without any official recognition." In other words, there's no proof you audited the class or even paid attention to the lectures. You simply sit in on the lectures. This is opposed to the Pass/Not Pass system, where you only need at least 70% to "pass" the course, thus receiving a formal recognition on your transcript along with units. I don't care about the units, but moreso the recognition that I actually went to this class, paid attention, and learned something. Would grad schools see me taking P/NP as a failed attempt of doing well while trying to scathe by, or an 'intellectual' curiosity to explore and audit? I fear that taking the normal route of 'auditing' has no proof and grad schools would see it as a lie to pad my resume/transcript. This P/NP route would give evidence to my auditing, but could lead to these other implications I fear. P.S. I know it's bad to think in terms of grad school, but unfortunately, it's a necessity to 'consider' their viewpoint for practical reasons (i.e. going to grad school).
