There are those of us who want skipping an answer to be considered answering a question, though. I am trying to mimic a classroom activity that had to go online because of the COVID-19 shutdown. In class, it used an audience response system and students were forced to answer then and they could not go back and if they didn't answer in the time allowed, they didn't get to answer. The question was shown on the screen, not on their individual computers. Except for the time limit being on the entire quiz rather than individual questions, this works well for me.
I don't follow your comparison to paper exams. On a paper exam, they get to see all of the questions at the same time and they can go back and review and change as many as they want.
The setting that most closely mimic a paper exam would be to not check "one question at a time" and, if you did, you wouldn't check "lock questions after answering." It really sounds like you want to deliver one question at a time but not lock the questions. This functionality is already supported.
What happens is most students do not return to questions they answered right away, so leaving that "lock questions" unchecked won't affect them. But it will allow students to go back and answer questions they couldn't answer.
In Classic Quizzes, students can flag questions to return to: How do I take a quiz? and How do I take a quiz where I can only view one question at a time?
In New Quizzes, students can pin questions to return to: How do I take an assessment in New Quizzes? and How do I take an assessment where I can only view one question at a time in New Quizzes?
