Ability to have quiz score requirements, and allow attendees to retake quiz

Our company has been looking for a way to add quizzes to our webinars. We have a very specific requirement: the attendees must score 70% or higher on the quiz, and they can take the quiz as many times as they need in order to get a passing score.

I could only find one company that allows for this functionality, On24, however they are built towards larger companies as they charge upwards of $10,000 a year. Please add this feature to Zoom webinars!
