I'm in high school and am very frustrated by how easy "physics" is. I really enjoy the subject but feel it's watered down in my school, and apparently my state. I would like to do some more complicated problems that only cover intro to physics, but are very complicated in that you need to actually think. I'm bored with physics in my school. My calculus is not good enough yet to do complicated calculus, so I can't do that. I want to challenge myself.
