Hello Subhanshu,
It totally depends on examiner. Most probably he is not going to check your half answer but there are some chances if you have given the question no. in the next half part of your answer.
Best of Luck !!!

Hello aspirant..
It is not so as you think.You copy will be thoroughly checked.Every copy is checked carefully and thoroughly.Therefore don't mind it.Be sure about it.
It is responsibility of the teacher to check the copy well.
Hope it helps you.
Best of luck.
