I'm a high school senior in AP physics B, and quite frankly I'm bored to death with what were learning right now. I've gotten a little case of senioritis, and I feel less and less like trying to be interested. So with that said, would it be advisable to just read further on into my book and try learning about more modern(and possibly interesting) theories that my teacher won't be covering this year? I've really always wondered what Einstein's theory of Relativity was all about, and there is a whole chapter in my book covering it. The reason I ask is because I just don't want to get in over my head. Keep in mind that I've already practically finished all of AP Physics B and a normal physics 1 course at my high school (pre-req). So would theories like relativity be too advanced for me to try and self study?
