We are using multiple answer questions in a quiz. Most of these must have 2 or 3 answers selected (which each have a rating of 50% or 33%) to be correct.
The thing is, for the question to be answered correctly, they really need to achieve 100% by selecting all of the correct multiple options. If they select a wrong answer, we have that covered by setting the answer to -100%.
The problem lies in the grading of these questions. If they select 2 of the 3 correct options, they receive 0.7/1. This causes problems if they get 2 partially correct answers in the quiz which then may tip them over a pass mark, but in fact, they have answered both questions incorrectly which would be a fail.
So the decimals are addding to the grade in a way that is causing problems. If we set the decimal to 0, then the number is rounded up, so a mark of 0.7 becomes 1, which is then seen as correct.
So, is there a way to either set a question so it must reach a mark of 1 to be correct, or drop the decimal from the question grade without adding it to the quiz grade?
