Need "cooldown" period in quizzes

[MmagdyHafezZ]

We have some quizzes that are very sensitive to a learning just trying to brute force the answers. Some of our courses give incentives (dollars) to business partners ans so we need to make sure the quizzes for these courses are not random guesses over and over.

To help prevent that, today, we use a "cooldown period". The specification is

1. how many times can a user fail the quiz before cooldown takes effect
2. how long is the cooldown (in hours and minutes) where hours could be a large number like 5 days (120 hours).

The learner is then prevented from taking the quiz again after they have failed N times and muse wait M hours/minutes before they are allowed to make another attempt.
