How to know that the question is posted previously.
In the practice test some submitted questions are deleted for the reason saying that already posted and duplicate question. So, my point is that how to know that whether a question is posted previously or not.I know that to search each and every question in the approved page, but this would be possible at present as there are limited question, but when more members would post then the particular question would not be easy and not possible to search every of the question.
