So, true story, back in 2010, when I took the fundamentals of surveying exam, I had convinced myself so thoroughly that I had failed it that I did in fact register for the April 2011 exam. They actually didn't prohibit such anxious unnecessary activity back then like they do now. When I found out I passed I actually had to call NCEES and PCS and tell them I had passed and that I was a ******* and needed to cancel my registration. They accommodated me easily enough. I hadn't actually paid yet, so at least I didn't have to deal with getting a refund.
