Answering a question in c.s.s depends upon the nature of the question..

There is no hard and fast rule that u follow this and that pattern or write in a specific way..

The only criterion are that u should be focused, updated, informative, organised and free from irrelevant material..

If u follow these than whichever pattern (outline, subheadings etc) u wish to adopt u can adopt..

All is that ur content should be good and organised..

I gave outline in almost every question of every paper.. let's see whats the outcome..
