The first question on this exam shows correct choices in green when answered correctly but the answer is marked incorrect for the question. This bug appears in several of the quizzes.
Can you share the exam URL? and a screenshot of the question?
@stevematdavies , Which question are you facing the issue? I have checked the Q1 and could see the answer is correct.
My bad, I had some cache issues when opened a new window, all is well now, it was the same when doing the other tests, I sometimes open them in new tabs / windows and it seems to mess things up
