Hi,
This situation saying on that time when you fail in your exam or your certificate not issue. You contact your school first because they have a list of pass or fail. At first confirm from them. And do what they said.
Thanking you..

Hi Paramita,

First check whether you have entered the right details. You have to enter roll, number and date of birth. If it still shows the same try checking your result through SMS. Try this way: Text WB10< space> roll number to either of these numbers 54242, 5676750, 58888 56263.  

If the above ways do not work you have to contact your school. This does not necesarily mean you have passed or failed.
