Configuring Attempts and Feedback for Multiple Choice Questions

It doesn't appear that you are using the built-in question slides - or perhaps you are, and I do not have a strong grasp of the language.

The built-in slides have three layers: 

• Base layer (the question)
• Correct layer (shows when the correct answer is selected)
• Incorrect layer (shows when the incorrect answers are selected)

The incorrect layer will also show a "try again" button if you configure the question for multiple attempts - you said you want to present 3 attempts, so in the question configuration, you simply set that value to "3."

It also looks like you are using a "multiple response" question, not "multiple choice" - in a multiple response question, more than one answer is correct, and must be selected in order to pass the question. In a multiple choice question, there is one correct answer from the set of available choices.

Try using the built-in question instead, and that should help you.
