Hi there fellow comrades ( specially seniors )
well i am going to attempt the 2015 css exam and i am almost crystal clear about every tiny little thing except the horrible and scary " ESSAY"
the following queries need some special answers.

1-what is an outline ?
2-should we write down the essay like the English columnists usually do
(without headings) or should we proceed things with "headings" ?
3- how much we suppose to write on one outline ( heading) ?
will be waiting for your answers
