I want to encourage you guys that the number of the exam is not important at all. I took the test last week, spent 6 hours in the test room, and I was the last one in the test center. I got 265 questions with 12-15 SATA , 15 Calculations, tons prioritizes... almost questions are about med & surg, rare OB or Ped.
I just checked result yesterday....and it said "PASS"
So, don't give up if you got 265 questions, you still have a chance.
