GCSE History AQA Coursework

So I've finished sources A, B, C, and D (how useful are these to your enquiry into the threat of invasion in WW1 and WW2, 16 marks I think) and I'm pretty sure I've got really good marks.

I'm now doing 24 markers for sources E, F, G, and H and was wondering if there's anything I need to do differently to secure top marks. The question is 'how far do these sources support the interpretation that the main purpose of propaganda throughout WW1 and WW2 was to encourage hatred of the enemy?'

Thanks
