Like Shay mentioned below, this website is a work in progress and still being tested out, but right now the website is a supplement to what Shay teaches in class. Shay uses this in class and we mix in lecture, demoing, and lab work to help the Code Academy students understand the content. The students also use this to reflect back on what Shay has taught in the previous classes.

As of now, this is the best standalone resource, but it is a couple weeks old, so we will definitely improve it.

That actually makes a big difference. As a supplement to what's taught in class, I think the language is probably appropriate as it is.
