There's an excellent mind map of Internet practice sites set up to train pen testers by offering a place to practice their skills. Put out by Aman Hardikar, you can find the list here. There's also an URL only version here, which can be easier to read. Some of the sites are old, some brand new, and they are broken down into category for easy concentration on whatever you are learning. Aman has a whole catalog of other mind maps, found here.
