Nothing went wrong with my E.H paper. I came to know about the unforgiving nature of its examiners and its pathetic scoring trend only after I had wasted my time on it, so I decided to go along with it.

I didn't take help from any teacher, just took some basic guidance from a senior.

The length should be ideally between 4-8 pages (depends on the question). If you can adequately sum up all the information the examiner demands into 4 pages, good for you; if you need 8 pages for it, write you must!

As for the bit regarding headings, the techniques of attempting a question are the same for all the subjects. Go through this thread to get your query answered:-
