To add a quiz to your course, start by creating a new learning activity:

Choose Interactive Content (H5P)

Choose Quiz from the list in the H5P content screen.

Give your quiz a title and add the questions here:

In Grade - if you do retakes, default is unlimited. You can set attempts allowed and if it's the highest, first, last, or average score used.
Question behavior - I would leave this alone for now - it's more advanced options. Deferred Feedback is default.

Or

Instead of the H5P interactive Quiz, you can do it a different way.

Create a new learning activity and select Quiz:

You have many options here such as setting a time limit, or what happens if you get it wrong, or retaking the quiz or questions:

Grade - You can set attempts allowed and if it's the highest, first, last, or average score used. The default option for Attempts allowed is unlimited so you may want to change this, or keep it so they need to redo the quiz until they get 75% or higher for example. These options can be set here under Grade.

Question behavior - Deferred Feedback is default.

Overall Feedback - if they score a certain percentage you can write out instructions on what to do next based on their score.

Once you name the quiz and look over the settings, select save and display. It should take you to a page next where you add questions to your quiz: (question Bank)

There are many types of questions you can add:

A simple text field would be either "short answer" or "essay". The essay ones you have to look at yourself to see if it's correct while the short answer you can set it to score it automatically.

You can instantly provide feedback if they type in certain things. You can use this to explain why this is the wrong answer if it's a common mistake that you can foresee people trying to answer with.

If for example you made a mistake setting up a quiz and set the wrong answer to be the "correct" one, you can update it. Changing questions after people have done the quiz will give you an option to regrade the quiz.
