Help! A2 Comparative Coursework

Hi guys, I'm studying Pat Barker's Regeneration and Wilfred Owen's poetry for the comparative coursework for English Literature AQA specification B, but I'm really struggling. My class and I haven't really been given much guidance with how to do this coursework so we have all been set these two texts to compare, using our own question to link them together.

I have written about 600-800 words so I'm quite short of the 2000 word limit, and this is without really thinking of a question for my focus (I've mainly written about context so far). I'm really desperate for at least a B so I need to do well, but I doubt I will since the deadline is about 2 weeks and I haven't even thought of my own question. Do any of you know what I could use to compare these two texts? I have been advised setting or character but I'm not so sure as I don't think I could compare these very well. Also, would I be able to inbox you what I've done so far of my coursework so you will be able to help me a bit better?

Thanks in advance!
