Jeopardy is a bad example because you're required to wait until the end of the question before buzzing in, or else you are penalized.

Yes but if you don’t know the answer by the time the light goes on (the question is finished read), you will never get in. And if you buzz in without knowing the answer you will lose points. So you have to know the answer before the light goes , then be ready to buzz as soon as eligible. Jeopardy is a good example.
