Hello,
  
   Unfortunately you have lost the chance now. The last date for the submission of online verification of answer sheets for cbse has already been over. As per the rules of cbse, they give only one chance for this application which allows you to demand photocopy of your Answersheet and evaluate your answers. So now it is not possible to apply again for the verification without which getting photocopy of Answersheets is not possible.

Hope this may help!
