For Coding, you have three choices:
(1) Code.org Course 3
This is the easiest option we have, but there's nothing wrong with choosing it.
(2) Code.org Course 4
This one will challenge you more than Course 3.
(3) Codecademy -- Learn Python 2.
"Python is a general-purpose, versatile and popular programming language. It’s great as a first language because it is concise and easy to read, and it is also a good language to have in any programmer’s stack as it can be used for everything from web development to software development and scientific applications." (From the Codecademy website).
