Create an unlocking quizzes feature on our online platform

1. On backend (CMS page), a page called "Unlock Quizzes", where teachers/admins can drag and drop quizzes to arrange the order of the quizzes. 2. On frontend (student page), instead of showing the quizzes in "completed quizzes" and "incomplete quizzes", show a lock and its quiz name/folder under it. a. If it's a folder, just show the current folder image, with a small orange dot on the top right to show that there is a quiz (or more than one quiz) available to unlock inside that folder. b. If it's a locked quiz, show the locked lock picture (will be provided later once our designer finishes it) with a small orange dot on the top right to show it's available to unlock. 3. When students click the lock/quiz name to unlock the quiz, it will play the sound (see attachment) and show the unlocked lock (will be provided later). After that the page will direct them to the quiz start page, and the unlocked lock will disappear from that point of time. (Even later on when they go back to the quiz, they won't see the unlocked lock picture again). 4. Next level of quiz will be available to unlock when students score 85% or more in the previous level of quizzes. In this sense, it means teachers do not have to tag students quizzes anymore. Quizzes will be automatically available to students when they pass 85% in the previous quiz.
