I've heard that, and logically it makes sense - except that the
minimum number of questions is 75, so it's possible (I think) to have already failed (percentage wise) by question 74. But the computer has to give you one more to reach 75. By then it won't matter whether you get it right or not. But I think it's safe to say that if you feel pretty confident that you did well up to 75, and you're sure you got #75 right, you passed. Same could be said for getting #75 wrong - doesn't necessarily mean you failed, since statistically you could have passed at 74. Make any sense?

But, since the scoring system that they use is so "top secret" it's really hard to say for sure that my lil old logic is even close!!
