I am bored out of my mind at school.?

Middle school in entirety is such a joke. For high school, try to go to a magnet school. These are public schools that are focused on a certain part of studies, be it math and science, the arts, etc. Either way, in high school there is more variety to cles and some choose to take the most difficult cles and others just go the easy way and take regular courses. I don't see any reason for you to be getting B's and C's. You can't love to learn if you're not doing well in school, even if it's boring and dumbed-down.
