Well i am doing as Urdu Edexcel as well.... i don't really know but i think you should just follow the normal structure of answering an easy. i think you should structure the easy the way you would structure you GCSE English easy. Introduction, discuss given factor, discuss other factors andbalance your conclusion. i know its not a great help but at least that's what i would do :)
I have done URDU AS level and I got a C overall. But the essays just need to have a starting a middle and an end. You also need to make sure that your sentences are lear and they make sense as well as spelling needs to have extra consideration.
