Quite good but needs a bit refining.
.PROs.
The variety of different tutorials really helps to set out a broad range of knowledge for beginners allowing them to experiment. Easy to read text and the viewer can easily distinguish between AS2 and instructions. The cursor was a nice addition and the tutorial had a fairly nice layout (easy to use).
.CONs.
Important things such as onClipEvent();s needed to be explained, as that's extremely important for any flash game (which is what actionscript is normally used for). Some parts such as "Walls" and "Enemies" should have some explanation as they can be quite hard for beginners to understand.
Overall, this tutorial will give beginners some grasp on the basics of AS2 but the more difficult concepts need more depth. As for graphics, that isn't much of a concern to me but perhaps it's worth looking into. 64/100 B-
