Wrong barcode sticker- company law exam

You need not worry, Affixing of Proper Bar Code Sticker is the Job & Responsibility of the Centre Invigilator & Centre Supervisor & Incharge. You are not even required under any authority to check that or question them, If any mistake is done therein they are answerable for that & You cannot be Penalised or be affected party for such Mistake.

Then wher did you sign on the attendance sheet ? Was it against the bar code of the next days examination. Not possible, because the invigilator will have to do the count of number of candidates present and absent both physical count and from the attendance sheet, to tie back the numbers. It is not possible only your sticker is removed from the next day exam on the attendance sheet and all others is in intact.

Anyways, hope they would have rectified at the stage of final reconciliation of total candidates appeared and absent. Don't worry now focus for your SLC examination.

All the best.
