I think maybe you need to take a step back first and foremost. You aren't going to perform well when you are overwhelming yourself and your brain so much. Take a day and then come back to it with fresh eyes. Worst case scenario you take the test again at a later date. When you feel refreshed again go back to the basics, review the core curriculum, and remind yourself it will all work out the way it's meant to.

I wouldn't risk it. When I tested remotely, they had an issue with everything from my bachelors / masters degrees on my wall to the length of my fingernails :))
