There is lots of legal study material out there. Here is just is some of it. Yes, in some cases you do have to sign up to get access to the free stuff but what do you expect these companies do need to make a living too.
BTW if you want to confirm that website is selling or promoting legal material, I recommend that you use CertGuard to confirm the source. http://www.certguard.com/search.asp
Each one of these companies has some or all of their exam software with demonstration versions.
