Well, to be honest, I don't have a favorite. Most of the classes are useless or painfully boring. English is OK, but the books assigned are usually tedious and grammar is a thorn in the ass. I really would like English if I got to choose my own literature (at grade level, no Magic Tree House Books) and got to choose what to write about.
I hate what I'm learning about at math. I do well in it, but a lot of the stuff confuses me. The only joy I derive from it is the satisfaction of finally figuring out an answer.
Science is confusing, especially when you get into the chemistry and physics, see math.
Social Studies is the easiest course, but the only things that interest me are economics and psychology, which are rarely discussed. It would be more fun if the class could debate politics instead of remembering obscure factoids.
I'm not artistic, so no arts for me.
PE is relief time, essentially. I have to exert very little brain-power and ace the course as long as I participate. It does get a bit of an inferiority complex in my head, though.
Foreign languages are boring, at least for me.
I guess I'd have to say "other electives" since that could mean anything from Business to Journalism.
