Central Board Of Secondary Education [CBSE] — Biology cbse boards paper

Sir I know I am amongst 1024 aspirants complaining about various issues. But I'm left numb after the biology 2017 cbse boards paper for which I had spent months preparing. Yes the paper was very easy but was lengthy at the same time which led for my uncompletion. I could not complete my paper but had well explained most of the questions merely . Having prepared so much and leading to this situation has left me with nothing but the fear of not scoring in the subject I had always put my best effort in. Please sir, I know each and every student has a request to make but I'll be very much grateful if you provide me with some grace marks so that this boards turn my career much better
