Display quiz results for users I am developing an e-learning portal for a client; the client wants to be able to create quizzes and view the results of individual students, and probably draw a graph to give an overview of student performance. I am using the Quiz module to create quizzes.

The "quiz score" is not available if you use node as the view base or quiz.

I am able to list username, level, and quiz.
You would need to add a relationship which would be the Quiz Result : User. 

Then you would find the quiz result : score in the fields
