First, you need to decide what you want to work with. Animation in particular is usually found in schools under the "Cinematic Arts" category, with Bachelor of Arts and Bachelor of Fine-Arts degrees.
If you want to become an animator (in a more broader term, an artist), I would seriously avoid the Computer Science and Mathematics programs. These are not artistic programs and will not help you develop the necessary skills for working for a studio. Furthermore, these courses won't have you building an animation portfolio or demo-reel before graduating, something that's essential to get work.
Second, you should always keep an eye on your dream employers, what kind of job openings that they have and what are their requirements. Some also offer internships.
Start to look at things from the professional point of view, instead of the consumer point of view. For instance, Disney has an entire website dedicated to careers in their various studios and departments, which the common public doesn't usually access.
You can get more information on education in digital art forums:

The most important thing that you need to know is this: if you really want it, then there's always a way.
