You can select a grading option for the question. To award partial credit with a penalty for the question, click the Partial credit with penalty option [1]. The Partial credit with penalty option awards points for each correct answer selected and deducts points for each incorrect answer selected.
Partial credit is calculated by dividing the total points possible by the number of correct answers for the question. This amount is awarded for each correct answer selected and deducted for each incorrect answer selected. No points are awarded or deducted for answers that are not selected. Zero is the lowest possible score. For example, if a question is worth 4 points and there are 2 correct answers, Canvas divides 4 by 2 and awards 2 points for correct answers selected and deducts 2 points for incorrect answers. If a student selects 2 correct answers and 1 incorrect answer, the student will receive 2 points total (4 points awarded for correct answers and 2 points deducted for incorrect answers).
To award points only for an exact match, click the Exact Match option [2]. The Exact Match option only awards points if all correct answers are selected and no incorrect answers are selected.
