I did bubbled in exam but QR was pasted what Will happen for CA inter exam

I do not think the question was clear enough for me to understand the issue. The QR code is pasted to prevent any malpractise. Once the QR code has been pasted, it will show some results:

Level Low L: 7% of the code words can be restored

Level Medium M: 15% of the code words can be restored

Level Quartile 25: 7% of the code words can be restored

Level hIGH h: 30% of the code words can be restored

So in the exam hall or when your paper is being scanned, even if is at Medium level, the chances of your paper being corrected are good enough. But if it is Level Low, then you need to contact them at: intermediate_examhelpline@icai.in to check the next course of action.
