Please before going to attempt CSS ,
let us have some grammer practice collaborately.

In an essay just write what you really pain for Pakisatn.
just write what is solution of these pains to medicate.
Write what you feel that it will ameliorate or not?

Go with a stance saying yes or no to your heart and convince examiner that yes you are hundred percent right by giving all your valueable arguements.

He will never fail you .

Trust me.

Regards
