How do you upload missing documents to the university start page?

Hay!

I have to upload my certificate for my application to ASH (Berlin). I was only able to apply there with the Hochschulstart platform. Unfortunately, I don't know how to do that. I actually sit in front of my laptop for hours, but I don't know how to upload documents.

By first using the correct form of the third person singular ("loading") and then writing "in V (!) oraus".

Any Neanderthal man should be fine with PC technology - nothing against this species! - Be superior.
