What I found disconcerting wasn’t the “return false” but rather the else: “You have guessed incorrectly, but may move on.” It there returns true, indicating a correct answer, and allowing the student to proceed, even though the answer was not correct.

(I’ve already forgotten the context, but I think “correct” is computed just above this snippet.)

Now, having critiqued the code, I must say I’d rather not give my doctor two guesses to diagnose me. TV’s “House” seems to need three guesses with the first two generally being fatally wrong.

How about this:

if (!ocrrect) SendToUser(10000 volts);

I think you’re misreading the code. The method returns false to allow the student another “guess”. Assuming “correct” is global, rather than local, the caller might read:

while (!GetAnswer());
if (correct) score++;
