For multiple-choice questions, the sum of the grade ratios for each correct answer must be 100%.

Set the percentage of grade for options considered as incorrect to '-100%'.

EX. four options (2 correct/ 2 incorrect answers)

→ correct answer 50%/ correct answer 50% / incorrect answer -100%  / incorrect answer -100%

EX. five options (3 correct answers / 2 incorrect answers)

→ correct answer 33.333% / correct answer 33.333% / correct answer 33.333% / incorrect answer -100% / incorrect answer -100%

(Note)

• If the student choose 1 correct answer and 1 wrong answer for 2 correct answers, the student will get 0 points.
• If you select only one correct answer for a question with two correct answers, a partial score is accepted.
• When ratio of grade for incorrect answers is set to 'None', even if both correct and incorrect answers are selected, if all correct answers are included,, if all the answers are included, it will be treated as a perfect score.
