I want to complaint to cbse that 1 question came in 10th class exam that was out of syllabus!!
The question was of article writing with a choice of letter!!
But i made a grave mistake by writing article in the form of letter and i am feeling very low and sad!!
Plz tell that will i get zero or grace marking would be there as my content was 97 larceny correct but i wrote letter instead of that article which was asked!! *
