Set up the answer key.
Click on the first question that you would like to grade. You'll notice that there is now an Answer Key link at the bottom of the question. Click it.
Select the correct answer and assign a point value for the question. You will also have the option of giving feedback for correct and incorrect answers, but this is optional.
Complete this process for each question on the quiz.
View the results.
Once the students have submitted the quiz, click the Responses tab on your form. It will default to the Summary view.
This will show you a summary of all of the answers submitted for each question! I love the graphs for a quick visual of how students did on each question!
If you would like to see a specific student's answers, click the Individual tab. This will allow you to view each submission individually. You can even print the individual quizzes!
