Gametutor :-)

One of the only Houdini courses available on here, but not great. The entire first half of the videos on here are almost inaudibly quiet, he makes a lot of common sense mistakes throughout, and he completely bypasses vital information. As an example, at one point he merges two lines, then directly references the point numbers of the resulting lines in a later node.
The problem here is that the resulting order of the point numbers will be completely different depending on the order in which you connect the nodes for the lines being merged. I happened to connect the two lines in a different order, and spent a couple of hours trying to figure out why everything was wrong.
As another example, his strange and inefficient approach to creating the stairs leads to the whole network being twice as big as it needed to be. I was able to recognize and correct those things while I followed along as an absolute beginner, so I have a hard time understanding how the instructor couldn't.
