Extra Credit in Assessments for Answering More than a Minimum Number Correctly

A faculty wants me to create a quiz with 17 questions. If the students get any 15 correct, then they receive 100%. Any correct answers above and beyond those 10 will be extra credit points. How do I do this in ANGEL without manual grading? We would also like to preserve the ability to randomize the questions.
