Database - Communities Applications Form

Hello there I am creating this dashboard for communities, so here is my idea I am trying to create. I am trying to create a application dashboard, where each community can set there own questions for a application, where staff can review the answers in a control panel, I’m not sure on where I am going wrong with this. Im teaching myself because I dont get the tutorials even know I have done them. I mainly struggle with the repeating groups one. Here is what im trying to do…Its basically like a test, where they can review the users answers, If that makes sense.

Any help would be much appreciated. Thank you. (I have set the link above to public so people, can help me out if possible. Thank you in advance.)
