A couple of times I’ve accidentally clicked twice in rapid succession on the “Continue” button, and the second click has been interpreted as an answer to the next question. (I think it happened to be a correct answer both times.)
I suggest disabling the buttons—or at least the “B” ones—for about 100ms after displaying a new question.
