Hi Wordmax,
just like a real-life exam/quiz, if a user decides to not answer a question (or misses it), then then they are not awarded points.
If you really want to force a user to answer each question, then I recommended enabling the “timer per question” feature. With this enabled, only the “current” question can be answered.
Thanks for your review and please don’t hesitate to ask for support inn the future ??
