There is an error in this quiz, it says that you can use ? in a Ruby method name and I believe this is incorrect.

Hi Derrick,

Sorry, no error in the quiz. :)

Methods can have a question mark in the name (variables cannot) but only at the end of the name. So, def method_name? is valid, but def method?name is not.

When you end a Method name with a question mark, it will return a boolean.

You can read up on some of the naming conventions resources I've found for you. There is github, a blog post by Paul Gross, or the Ruby Learning site.

Hope that helps clear it up for you.

Keep Coding! :dizzy:
