Must answer question to exit

Not to open a new topic.Is there a way to make some of the questions mandatory to answer correctly in order to pass the quiz? Fot instance 2 of 10 questions must be correct, but all together 80% should be passed.Should I use the condition action if a user answers incorrectly, she/he is brought back to beginning of course? Is that the correct way to go?Thanks.
