1)I’d say it’s worth going to as long as you’re willing to put in the effort yourself. Even seasoned animators improve based on exposure to the people here and feedback from the instructors.
2)I’m a part scholarship student. They gave me one term for free in both the foundation and 3d programs that I took(am taking). It wasn’t too hard for me to get it, just submitted some work I did and your reel may help you. They do have scolarship periods though so call your respective counselor.
3)Collaborations are doable though not advisable as a main focus as each person will have a huge workload and won’t be able to dedicate time. He can do your final but it’s probably not inn his best interest to do it as his final(as a side project maybe though) as Sound design students can ask professional studios for permissions to videos.
4)Some people travel. 3D people don’t really. Too little time.
5)Yeah getting work is hard, but it all depends on your final portfolio.
