Thanks. I've got a new piece of software which is helping loads. Basically, you put all your ideas, quotes, little bits of info etc. down and then you can pull them about and reorder or change them. Then you click a button and it writes your assignment by stringing together all your ideas.
It's much better than having a dozen pieces of paper with scribblings on and words everywhere. You can even add pictures, draw, change font, add colours and loads of other things.
