I have a suggestion. It may seem stupid, but it's actually pretty good. It's not free, but you may be able to get by with an e-book.
It's called "Torque for Teens"

It's what I used when I started using Torque. It doesn't only go into scripting, but also in-depth on how the Torque Game Engine works.
Books are very helpful when learning to code with any game engine.
I have books for alot of different stuff.
And when reading something, that IS teaching you. You might have luck in college, but not on the internet.
You could also try online guides.
