soonCPA,
I would think that if you feel like you're close then you're probably close. Nobody is really sure exactly how everything is curved at the end — but keep in mind that many questions are pretest items and don't count toward your score at all. In BEC, AUD, and FAR, 5 questions a testlet are pretest items, and in REG, 4 questions per testlet are pretest items. In all the exams that have writing sections, only 1 of the 2 communication tabs are scored (ie one counts for all 10 points; the other counts for 0), and some tabs are also pretest items and don't count at all. So realize that if you feel like you're on the fence then really ANYTHING can happen…the stuff that you weren't sure about may not have counted at all!
Good example of this…when I took FAR I thought I had gotten half of it wrong…no way in the world I thought I passed. I ended up with an 80. Then, when I took BEC, it felt pretty good…so I thought I passed. I ended up failing with a 73. I joke with my friends saying that I definitely nailed the pretest items on BEC…but really though you never know what'll happen until the score comes out. Stay confident and focus on the exams you still have left to take.
