How much to write?

in the theory you should write the answer according to the question demand. it will be even fine if u have written only 1 page but it should be high quality answer

i have also done this in exams

Dude u better know pages of answer doesnt matter at all in CA 

but ambiguity arises when a 10mark question asked and you have only half page to write ..........

in such case try to elobrate your answer with the quality lines and ya one page is enough...

quality is more important than quantity

Quantity doesn't matter in your answers.. Its quality thats show your answers..

Fully agreed wit Ruchi's view

To the point answers serve the needs better than filling up the pages. However one should keep the marks for which question is asked.
