While Displaying Interview Question Answer ( Objective ) - It showing us > Show Answer. When we clicked on that linked, Correct Answer being displayed with a "Tick Sign" and answer color changed to green. Now If I click on Correct Answer Again , Tick Sign Disappear but correct answer color still showing green.
Now, It would be better if you can change it like "Show Answer / Hide Answer" . Means when user clicked on Show Answer, the text will changed to "Hide Answer" and click on it - Reset the questions.
Hope you got my point. This is just my suggestion.
