Hi Wajahat,
writting in our own words is very good thing, but it should not be difficult for checker to understand whether what you have written is right or out of subject.
see practicaly when anybody checks exam papers, keep one answer book (master) with him or her.
or select one best written paper as his/her reference (master) for further checking.
If your written answer( even I should say Answer's major points and Titles) matches with his/her master then checker will give you good marks and proceed further.
(

remember checker dont have only one paper to check...)
Mind well I am not commenting the way AMIE checkers do their work, It is the human tendancy I am talking about.
because I have some time had checked question papers in my past, writting this with my own experience.
do your best preparation for exams and remember you must know the ART of showing your knowledge to checker, It is the key of success.
with the addition of that you can refer some good posts on the same site about study and question paper writting,
hope it will help you.
