This time applying for DAAD scholarship is online portal. But unfortunately, I thought that Motivation letter would be only required. However, as you will be seeing in this image attached with message that CV and Project proposals are mandatory to be online uploaded . But the Motivation letter is mentioned to be mandatory submitted by post along with other certificates.

I wrote the motivation letter very well.
However, I didn't write 'Project proposals' .
I think that Project proposals is much more difficult than motivation letter since it needs Guide for Writing Project Proposals.

Thus, I would like anyone to kindly tell me if:

First: Is 'Project Proposals' the same 'Motivation letter'?

Second: what is a short description of Short description of research,study,work' and 'Description of research topic'
