Provide improved Studio quiz functionalities

[Dalma_Schnell]

Theme Overview

Expanded quiz creation and editing functionalities, more flexibility for user controls, improved feedback mechanism, and always available usage insights.

What value could this provide to users?

• Able to rewatch Studio quizzes without retaking a quiz, so I don't need to take the quiz every time I want to watch only the video.
• Able to edit quizzes and auto-update grades accordingly after students have taken the quiz so that I don't need to recreate the whole quiz because of a mistake.
• Able to use a rich content editor and open-ended questions in Studio quizzes, so that I have flexibility while writing questions and comments.
• Able to receive immediate feedback on the question that I answered in Studio quiz so that I don't need to wait to find out if my answer was correct until all the questions were asked.
• Able to add more levels of replying in Studio Quizzes, so I can help promote discussions.
• Able to access insights in all kinds of Studio videos, so that I can always know how viewers interact with and view my media.
• Able to prevent students fast forwarding studio quiz videos the first time they are seeing it so that I can make sure they watch the video at least once before answering any questions
