With your student discount it's ~$100 or so... I think ~$250+ if you aren't a student. Depends on how many of the 3 sections (music, film, internet) you choose.
The whole thing is a blast, some of the best in all 3 industries are there, seminars, demos, panel discussions, etc... the night parties aren't bad either since it's in Austin

It has always been in March, and probably will be this time as well. Check the site occasionally for updates...
