Not TTC related but — NCLEX today!

I need somewhere to rant because I haven’t told anyone in my personal life that I’m taking the NCLEX today out of fear of failing. For those that don’t know what it is, it’s the board exam we have to take to become a Licensed Registered Nurse. I’m so nervous I feel like I could upchuck at any given moment. I take it at 2 today. Any RN’s with advice or tips and tricks??? I’ve studied mostly ATI and have tried several other free practice methods (including Kaplan, NRSNG and UWorld but they only give you 5-10 questions each without paying the full price). I’ve also used the NCLEX mastery app, Lippincott and the RN Mentor app. Recently took my ATI NCLEX comprehensive predictor and made an 80% which translates to a 99% chance of passing NCLEX.
