I am in Calculus BC in high school right now and I am really enjoying it and have finished all of the material for the year and I have heard different things about what class comes after Calculus BC (I believe BC is equivalent to Calc 1 & 2 in college). I have heard the next class, aka Calc 3, is vector calc from some sources and multivariable from others and I am wondering if these subjects are similar? and what differences? and what comes first typically? Additionally, I have heard that you need linear algebra for vector and multivariable so I am wondering if THAT comes first?? Basically I am confused on what I should focus on now that I have finished Calc 2. I have tried to look up what comes next, but again I am getting mixed answers. Any help telling me the similarities and differences and what I should study first would be of great help! Thanks!
