Hey, I think you have a mistake. In your controller quiz, you have:
2. What is a Controller?
A Controller are PHP classes that are designed to work with information in your database
A Controller is simply a class file that is named in a way that can be associated with a URI.
A Controller is simply a web page, or a page fragment, like a header, footer, sidebar, etc.
I don’t know
But the Controller is a layer in the MVC design pattern which handles the business logic between the view and the model..
i’m probably being anal anyway...i got 100% :-D
