Confused and worried about my NCLEX experience!

So heres the thing. Im a Canadian RN, have been working since 2007. Since Im looking into going to work in GA, I had to write the NCLEX, and think I was fairly well prepared for it. I studied and came on here a lot for strategies. Then I also read about how getting a lot of SATA questions is usually good, so I counted more or less how many I got, and was given like 15 or so. I was feeling pretty confident because of that, so my heart sank when I wasnt stopped at 75 questions. They did however stop me at 76... Now Ive been stressing myself out with that darn 76th question!! Why give me one more?! And my mind blanked after the test stopped so I dont even remember what the question was or even if I was sure of the answer...I am going to be so stressed until I get the results...48 hours can NOT go by fast enough!
