Central Board Of Secondary Education [CBSE] — to provide grace marks in accountancy

Sir,
The accountancy exam which was held on 6 march 2019 had a mistake in q-14 in all the 4 sets. The question was of dissolution in which we need to prepare realization a/c but the question was wrongly printed and asked to prepare revaluation a/c. So we got confused between realization and revaluation a/c. So we demad for a garce of 6 marks because of the mistake done by cbse and because of which westudents need to suffer and much time was exausthed in that confusion.
