I'm not sure for how long this has been available : if you are a student, you can freely access the CAST training system for NX. CAST is basically a very helpful set of tutorial based training that covers modeling, assemblies, drafting, machining, simulation, etc. (the abbreviation CAST stands for Computer Aided Self Teach)You'll need an email address that ends with ".edu", ".ed", ".ac.uk" to register:

Existing CAST owners : here's a tool that will help you to create your own set of trainings: http://cast.ugs.com/ccb/index.shtml
