Just downloaded and testing out this plugin. When I complete a quiz, is there a way for the admin and the quiz taker to get the results to there email immediately?

Is there any excel or csv importer option available for questions?

How to email id make optional? and how to show the correct answers and score to the user at the end of quiz, after submitting name?

When you create a new quiz, fill in the question fields and click save, this error appears.
