Nodes show up differently in Blender than they do in the tutorial that I'm following.

So I’m following a good tutorial on making manga-like eyes in Blender. However, the version of Blender that he’s using is a couple years old and I’m afraid that this is what my problem is here. My problem is that when he shows the nodes in Blender, it’s different than what my program shows. Here is a timestamp of the video I’m watching:

And here are the nodes I’m getting in the program:

And of course here is the link to my current progress: http://www.pasteall.org/blend/39382
Can anyone help please? Thanks!

The tutorial shows shader/material nodes (green arrow), your node editor is set to show compositing nodes (red arrow):


Ah, thank you. Haha…
