You may want to create a quiz or test in which students will only answer a portion of the questions. For example, you may offer ten essay question choices to students, but instruct them to choose five to answer. In this case, you will need to configure your Moodle quiz to weight the assignment properly, so the students aren't penalized for not answering questions.
Moodle assigns a "mark" value to every question in a quiz assignment. The mark value is the relative weight of that question, as compared to the other questions present in the quiz. For this, you will need to know the total of the marks in the quiz, as well as the highest mark you expect to give. Marks are separate from grades at this point.
In our aforementioned example, there are ten total questions in the quiz. If each of the questions has a mark value of 1, then the total marks of the quiz is 10. Since you are asking students to answer five questions, the expected mark is 5.
As our hypothetical quiz stands, your students will receive a maximum score is 50%. To adjust this, go to your course gradebook, and then to categories and items. Select the edit icon next to the quiz, and then look for the multiplicator field. The multiplicator field will multiply students' final scores by the value placed into it. To find the proper multiplicator, divide the total marks by the expected mark. In our example, the correct multiplicator is 2. A student who answered five questions correctly would then receive a score of 100%, rather than 50, while a student who answered three of the five correctly would receive a 60% instead of 30%.
N.B.: This method will only work on a quiz in which all the questions have the same weights. If your questions are weighted differently from one another, the multiplicator will produce inaccurate results.
