The learn tab, which for some reason includes a lot of stuff that isn't learning related. Also for some reason, other than the Web Learn link, all of these are hierarchies pointing to a single application, which seems pointless.

It was hard to get a screen capture of this, but this is the paint program, which runs full-screen.

Also full screen, but kind of broken by the screenshot utility, is Tux Typing, which is listed under Language which seems out of place.

The web learn points at a thing called Skool (although stylized Skoool by Xandros, again for some reason), which appears to still exist but is predictably broken on here because of HTTPS.
