sit i have forgotten to write Q. no in bk paper and maybe it was last and second last question which was compulsory to attempt which contains 15 mks and 12 mks each so they will reduced my whole marks in that
Hello Aspirant!
CBSE generally thinks about the welfare of its students. So, although you have made quite a silly mistake by not writing the question numbers of the questions containing 15 and 12 marks respectively, you can stay hopeful. It depends a lot upon the Examiner evaluating your answer script. If he/she wishes to consider your mistake and be merciful, you will get marks in those answers if they are correct.
Best wishes!
