This is possible, I have two workarounds in mind.
Method 1: You can manually assign calculation values on the question answers or via conditional logic. You can then perform form calculations using the form calculation widget. You can then display the total score to the "Thank You" page or in the email notifications.
Method 2: This is by using the Quiz App, you can check this app page: http://apps.jotform.com/app/quiz_form
I hope that helps.
