For my freshman year, should I take AP Precalc AB or BC? If BC, should I take Multivariable Calc & Lin Alg or just AP Stats for my junior year? If I take AB, that means I will most likely take Calc BC in 11th grade, which doesn't sound too appealing. The idea is if I'm taking BC, I could directly go on to Calc BC for sophomore year, so I could have my 11th grade year easier and just take AP Stats instead. However, I'm just worried it will be too much to handle.

I'm currently a rising freshman and I've taken all previous math classes before.
