Not to necessarily worry. I sat for the first computerized boards and was CERTAIN I would fail...not confident at all. When my computer shut off at 75 questions...I was mortified. I was CERTAIN I failed. Rumor was if it shut off at 75, you either had enough right or enough wrong to pass or fail...well DUH!!! Same could be said about the whole taco. I understand that statistically, that even if you have answered enough questions to have passed the exam, the machine might not shut off because a certain percentage of people taking the exam will be forced to finish the whole thing for whatever sadistic reason the boards have. Don't fret too much. Wait and see like the rest of us did and then rejoice when you find out you passed.
