There is a short cut dears, which worked.
Once I submitted my online application form with some mistakes. After editing it was not being change.
Then I applied again for the same post with the same number of Bank Challan Receipt, everything was the same, but the information this time was correct. Then I took the print of this correct form and sent my documents with it.
I received it's Roll Number without any objection. FPSC automatically cancelled my first form.
Means if you have applied wrong, then apply second time with right info. They will consider only those application forms online whose printed documents will also be received, remaining all will be cancelled.
