Hi there,
I'm sorry to hear about your waitlist decision. I know it's not the outcome you were hoping for but it's not a rejection - so you still have a chance! I agree that your GPA does stand out as an outlier in your profile but it sounds like you did as good of a job as you could have mitigating it. I still think it could be worth it to enroll in a class (statistics, econ, etc.) to provide further evidence of your ability to handle the rigor of the MBA curriculum. Even if you don't have a final grade by the time the WL is evaluated again, you'll be able to speak about the class in your update letter and you can share any interim grades. If you think you have upside in your GMAT score, then it can't hurt to re-take it and submit a new score that's 20 or 30 points higher. There's no way to say with certainty whether or not that will get you off the waitlist but it can't hurt you.
Otherwise, I suggest reviewing the waitlist instructions to see what other updates NYU accepts. If they accept new letters of recommendation, letters of support from current students, etc. then I suggest doing it all. You want to stay active and continue expressing your commitment to the school.
Without seeing your essays and resume, it's tough for me to say what specific updates would benefit you the most. It could help to have a third party (colleague with an MBA, for example) review your application and see what other opportunities you have to improve. If you wanted to engage professional help, that's something we could work on with you as well.
