Hello, so I am taking AP Calc AB this year, and I know AP Calc bc is the same as ab but then adds on additional units. After I'm done ab should I try and self study bc or would it be too difficult? I believe bc is supposed to be calc 2? I know Calc 2 is considered the hardest calc class. I plan to major in Math, and my school only has a calc AB class no bc. So I was just wondering. So after we are done Calc AB should I try self study BC? If we finish early, my teacher probably would help if I have questions.

Does anyone have tips for grammar, I have a friend who speaks polish. They don't really know how to help, they say it just comes naturally and can't explain it. Can anyone help me understand the 7 cases.
