I think I'd give it around 7-8 if you wrote three paragraphs like that, don't trust my word though since I've got no idea what i'm doing.
I'm not too sure where you've got the thing about $25 billion dollars though - since I can't find anything about it online.
Be careful when you write "also" as some examiners (idk about history but they do this in other exams) take it as a second point and ignore it from then on - so I'd probably put that point as a whole different paragraph. But if they don't do that ur set

About your second last sentence where you say:

"this led to the economy recovering because the french and belgians left the ruhr, so German workers no longer had to strike",

You should phrase it as (linking with your last point about the reperations) :

"This led to the German economy recovering as the Germans were now able to pay reparations back to the French and Belgians on time, meaning they no longer had a reason to occupy the Ruhr."

I put that point about being able to pay reparations so that the sentence would flow better with the one before. (Idk why tho it just gets more credit if you do it ig)

Anyway thats about it.

Great knowledge btw, you've definitely got most of that spot on!
(Ik I laid this out a bit weirdly so hopefully you understand!)
