In an all-or-nothing multiple choice question (MCQ), the answers chosen by a student must correspond exactly to the correct answers defined in the question. If this occurs a student gets 100%. If there are any incorrect answers or not all correct answers
are selected, the grade will be 0%.

Difference from standard Multiple choice questions (MCQ)
The main difference from the standard MCQ is in the way that grading works. In a standard multiple-choice question with multiple correct answers, a negative mark must be given to the incorrect answers to be able to make the grade 0%, however students
can still get a partial grade if not all correct answers are selected.
For example, if we have a question with two right and two wrong answers:
In the standard MCQ we need to award each of the two right answers 50% of the mark, then award each wrong answer -100%. If the student selects an incorrect answer, the grade will be 0%, but if only one right answer is selected, the grade will be 50%.
In the All-or-nothing MCQ, if the student selects an incorrect answer, the grade will be 0%, but if they select only one right answer, the grade will also be 0%.
One answer only MCQ
It is not advisable to use the All-or-nothing MCQ for questions that explicitly ask for one answer. The standard MCQ should be used if there is only one answer or if partial grades are allowed.
