they aren't as functional, and afaik, it hasn't actually been updated to even export fallout3 version nifs. So it won't do you much good at all.
Ghogiel is correct. the maya scripts haven't been updated since oblivion, so using them for FO3/FONV wouldn't work.
you might be able to do your modeling in maya however, then export the model into a format to use in Max or Blender. if you have access to Max at school, i'd suggest trying that. i'm not sure if animations will survive the conversions though.
btw i think you can get a license for Max (and other Autodesk apps) for free if you are a student. see here:
