What free/cheap interactive tutorials and lessons have you enjoyed?
So far, I plan to:
- Work through the Bandit box on OverTheWire.org [1]
- Talk about social engineering with the Social Engineer Toolkit [2]
- Practice CTFs with PicoCTF [3]
- ... hack the planet?

Affiliating a club with a national parent organization(s) may also provide additional resources.
