I have a History Controlled assessment on how useful *** sources have been in informing me in my enquiry into how conditions in the trenches of the Western Front in the First World War impacted upon British Soldiers there.

I missed the lesson where he explained what to do and he isn't a very nice person so I really don't want to ask him to spend time on catching me up, the rest of my class haven't been much help in that regard either.

What does the history controlled assessment involve? What are the examiners looking for? What exactly am I meant to write about trenches? Anybody direct me to some sample essays? What type of layout do the examiners like it to be in?

Any help on this would be appreciated- I am really stressing out :S
