For those who love to make quizzes here in Virily and have found this kind of problem in displaying correct answers in your quiz, here is a solution to rectify that.
Correct Answers not properly marked or clicked but upon constructing the quiz, they have already been marked. This is attributed to Internet glitch like weak connection, heavy traffic, or the site is overloaded or its server itself is disconnected.
After you are through creating your quiz, you submit it for review and assume that it is already intact. There is no problem. You may be right or you may wrong. It is better to check it. Meaning you have to go over it by editing.
Click the edit function. Then review your quiz. Sometimes you may see there are several similar images and much so there are duplicate answers or choices. You have to delete those excess and also you have to mark the correct choices.
Remember always review or edit your work after you submit it for review.
