Haven't actually downloaded anything yet so I don't know if it I some student version but it appears to be the ful software. If you are a college student, high school student, or a lying sack of s***, you can sign up and get pretty much everything they sell for free personal use. AKA no moneymaking.

Yup it's totally legal, legit, and free. All you need is an email ending in ".edu" I have autocad. I use it in one of my classes at school.

It's a 3 year license too.

I'm already under the DreamSpark program, although I might try this out for teh lulz (my course doesn't need CAD anyway hahahahahaha).
