What will if i have forgotten to write both set number and code number in answersheet during science examination of cbse class 10th?

Hello student please help me that where you mentioned to fill the set number and code number on your answer sheet/supplement answer sheet or attendance sheet. Because invigilator must check all the things filled in the answer sheet before signing the answers sheet. In case even if you forgot to fill it don't worry now prepare for your next examination and make sure you won't repeat the same mistake in another examination.
Feel free to comment if you have any doubt
Good luck
