Choosing a major
Your classes your first year (and much of your second year) will be the same regardless of your major. I think most declare their major during the first semester of their sophomore year (at least my son did). Prior to that time, everyone at the Academy will have taken calculus, chemistry, physics, history, english, engineering, a language (and more) no matter their major. So, you'll get a feel for what departments might best suit you. They also have "majors nights" (or something like that) where you go around to tables and talk to people from different departments about the available majors. And, since you (SAshy) will be on the baseball team (right?) you'll have a good chance to interact with upperclassmen who have a variety of majors and will happily fill you in on why they chose what they did. That being said - as others have mentioned, the Acadejmy is probably best known for its engineering degrees (degrees that didn't interest my son even though most of his best grades have been in his math/science/engineering-related classes).
