Hey @LauraJiménez !  I am am thinking that this could be done if you incorporated Item Banks into the Quiz.  Questions 1-3 could be added as individual questions.  Questions 4-7 could be added to an Item Bank and set to be pulled from the Item Bank which could present them in the quiz randomly.  Then questions 8-10 could just be added like regular questions, just as the first three questions were added.
