I've just started one of my courses, as classes just began 2 weeks ago, and we are learning Scheme right now in one for I assume some reason later on, but so far from what he is teaching is basically how to write in scheme. As I sit here trying to stay awake I'm just trying to grasp why I would want to know this, and why anyone uses it. What does it excel at? Next week I plan to ask him, whats the goal to learn here other than just how to write stuff in scheme.
Answer
It's a functional programming language and will do well broaden your experience.
Even if you don't use it in the real world doesn't mean it doesn't have any value. It will help you master things like recursion and help to force you to think of problems in different ways than you normally would.
I wish my school forced us to learn a functional programming language.
