5 in AP Calc AB, what happen if I want to self study and take AP Calc BC next year?

<p>Not OP, but I also got a 5 in AB would it be worth it to self study BC for my senior year? Here’s some background information:
Had a 99 average in AB,
going to take AP physics B, AP Statistics, and AP Economics senior year
got a 680 on SAT II Math II :(</p>

<p>is it worth it? I also plan on majoring in something with mathematics.</p>
