Quiz categories are very useful to organize quizzes for future use. Best practices dictate that in the process of making a quiz, the user makes categories first, the questions next, and the quiz activity last. This helps the user stay organized and reduces confusion in the process. You can create sub-categories, as well. For example: 
 
	 Module 1 Quiz
	 
		 M1...
