I am far from a media major, but I love to film and edit, In my opinion if thats what you really want to do with your life your probably already doing a bunch of it now, if not no better time then now to really get into it and make sure its actually what you want to do.
Just practice a bunch is the best advice i can give you, try to actually learn it not just going out hand held with a camera or a point and shoot snaping a few clips and calling it good. If you have a basic understanding of it when your going in it will make it that much more enjoyable and you will learn much more. There is a big diffence between a good artist and an amazing artist no mater what the trade they call their art. For a program like that i feel like if your just doing the course work and nothing else chances are you wont be making a living off it. Good luck either way
