Now that we've learned all about how to create classes and methods, in the 12th session we will learn how to create a Visualforce page with custom User Interface and leverage a customer controller to pass data between our code and the page. 

This session requires you to have a (free) Developer Edition org which you can use in all future workshop sessions. You can use an existing one, but since they are free & unlimited, why not get a new one? 

All previous sessions can be viewed on YouTube
