One last astronomy question..I promise

[Old Rusty Pipe]

There is this:

Astronomy 101 - Free Basic Astronomy Course - Introduction

It claims to be a 10-part lesson to teach the basics of astronomy. I haven't personally used it, or flipped through every page. However a sampling of the information on various pages was correct. I've taken Introduction to Astronomy and made an A, while tutoring someone else on it who also scored an A. I'm also an extremely avid space geek, so I already know most of this just from my hobbies. The site seems like its on the point with its info, and hey its free. I'm not sure how much of it would go directly to hitting topics that would be on the DSST for Astronomy. But with so few resources it wouldn't hurt to check it out.

Hope it helps.
