Which areas (chapters) will be covered in the test, and why was it chosen that way?

Controllers
Controllers are the gateway into an application on the server side of the application stack. To build a successful application, knowledge of routing, actions and REST will provide a solid foundation for an enterprise class app. Controllers, concerns and callbacks are necessary to be proficient with when working with a Rails app.

Models
Models are the data backbone for your application. Good data models allow you to store data efficiently, create data relationships and allow your app to scale and function properly. Rails provides excellent data tier modeling with ActiveRecord along with the ability to migrate and manage your data structures. All good Rails developers should have strong experience and knowledge in this space.

Views
Views allow the users of your application to interact with and work with the app. Without a view layer, most applications wouldn’t be able to function or provide any value. Rails provides good templating and view layers out of the box. Understanding how to display, modify and work with information from a User Interface perspective is a vital web developer skill.

Misc
The best developers learn how to work efficiently by utilizing tooling and tricks provided by the framework. Rails provides great toolkits to handle basics from code generation to advanced needs like background jobs. Developers can speed their development velocity by knowing and using the built in framework’s miscellaneous tools.
