Hello Student  You

Have stated that you have forgotten to sign on the hall tickets of 11th class examination. It is an act of absentminded and silly mistakes that you have done. so it is not so because the vacues exusing you for it you will not face  any problem. Most of the states has its own home centre for class 11 and 12 class examination. If you have exam centre in your home centre that is in your school then this mistake can be corrected on any day of the exam when the exam time will be exhausted after the exam. You have to request to the centre head for this correction of your mistakes. They  will accept your request and do you the needful.

Hope this helps.
