There will be a fixed amount of books. 9 books in total. Do you know the Bible app? Like that but without all the extra features. I just want the text (I have it on MS Word). Each book has 10 (short) lessons, so there needs to be some sort of menu to show the lesson. Each lesson has a quiz and a homework section (the homework secion is just text).
Now we want 2 roles of users (and a superadmin too, so he can see all the info). The Admin and the final user. The admin can see the progress of all the final users ASSIGNED TO HIM, so there must be a way to assign users to an admin in an easy way, maybe a way of inviting them via sharing a link or code. Basically there will be many admins. The user will be able to see the progress made, we will use the quiz completion to feed this.
This is the general idea. The app will be on the playstore and the appstore.
