Apps Database generated grid


Hello. I've been creating this app but i've hit a threshold.
The app is for a school enviroment, the idea is that the student will log in with his credentials and then the first screen will be a list of questions and observations.

The thing is, these questions and observations have to be submitted and edited by the teacher, they cannot be local or static, upon login the student's device should request a query for all the questions and dynamically load them into the app. How would i go about doing that?

Doing it locally my idea was to create a table with all questions, answers and observations, and feed a grid with them, but since they must be updated from an administrator...i don't know how to do it.
