"My point is: what is the reason Moodle lets you do 3 attempts as the first one is already meeting all requirements? If the student has its maximum score at first attempt - there is no need to offer another 2. It is already the highest."
Yes. Don't you think that the student will figure that out? Is there any harm if the student wants to take it again? Might you have some students who are "perfectionists" who might get a 95, but want to do the test again for a perfect score?
Relative to "pass/fail," I believe that you can create the logic in the student's grade book that anything below a score of 75 gets converted to a 0 (or even >75 =100.) Then tell students that this is why you allow three attempts.

As a suggestion, if you want to make this exam a little more challenging, create more (similar) questions and pick the questions randomly. This will benefit students who get a perfect score on their first attempt by allowing them more practice, and it will make the exam more challenging for those who do not get a perfect score.
