And outside of America, I'm pretty sure Electives aren't a thing. Or at least I've never heard of them.
The concept is this: Extra stuff you're not required to take but have the option to. It assumes your classes aren't planned out and that everything isn't required; the things that aren't required can be switched around with whatever you'd like. Those would be electives.

You've made a good start. A thread in the intro forum or a PM to one of us for any extra questions you might have could help you, but for the way the site works, you did it perfectly.
