I don’t want to demotivate you, but I think preselection made is false hope. I’ve never heard that it changed to funding. Rather stories that it is straight rejection.
I was meaning that if the status of others in portal is changing to Selection made, most probably students with preselection made get rejection. They had a lot of debates on this, in this forum, you can look previous years.
From my experience, candidates with preselection made get the straight rejection. Especially in Uzbekistan. Unfortunately, DAAD sends first approval of funding and then rejection, which is quite strange.
