Sharepoint Configuration - User Permissions, Site Creation

I need a sharepoint 365 site where students from the group "Abschlussprüfung" can upload files from word/excel/powerpoint. The users should not see the files of the others students. Please create a standard sharepoint site "Test" with a folder "Examen" where all the users of the group Abschlussprüfung can upload.

Please delete all other sharepoint pages with names like exam, examen, gafa-examen :-)

Sharepoint Admin User will be given!
