I don't even think it's neccesary to do that. ^^
Just go onto autodesk website, and register as a student. As long as you're not using it for commercial / profit use, they won't mind if you 'accidentally' enter a date of birth slightly incorrectly
- The worst case scenario is that it will not work. And if it does, well... It's their problem. Again, the only thing i'd recommend if you do it this way is to keep your models to yourself, and this community. If you start selling your creations some eyebrows may be raised.
On another note, I might give animating a try, but don't expect anything top-notch, and don't expect anything super quick, cos I have my own map to work on.
