Few details about the application:
The application works in both portrait and landscape.
It has a database of the questions.
Sharedpreferences are used to store the progress and history.
Library is being used to display the graph and fetch data.
The UX may not be top notch but it is functional and bug free.
The whole application is dynamic i.e., even if the data changes to add more categories/options/questions, the application will work reflect the new data once refreshed.
I have used cardViews, Collapsible ToolBar, FloatingActionButton, fragment, SnackBar etc., I could have used recycler views and viewModels but due to time constraints I decided otherwise.
Internet is required during fetching of data but otherwise everything works offline.
User has the option to Start/Resume/Restart/View History/Refresh Data.
Current progress is shown, along with '% chosen' for choices and if the selected answer is right or wrong.
