Online quiz that embeds hints if marked wrong

HI, sorry if this is in the forum thread somewhere. I read through a million posts and couldn't find an answer:

Do you know of a quiz creation tool where students can take a quiz online and if they mark an answer wrong, they would get a hint as to what the correct answer may be?

FYI: 1:1 computing school where each child has netbook, grades 6-8. PE teacher wants kids to take a quiz on rules before playing certain sports that has hints with in the quiz as reminders to reteach mid-quiz.

Thanks for your ideas!
