You've learned each tool on its own page. The exam doesn't tell you which one to use —
it just hands you a problem. This page mixes everything together: rapid multiple-choice where you
decide the approach, and a full free-response problem in the real Question 6 mold.
On the real BC exam, series shows up two ways. Multiple choice — fast, single-answer: which test,
what's the radius, which coefficient. And the free-response (almost always Question 6, 9 points,
no calculator) — one function, many chained parts that build on each other. This page trains both.
Mixed multiple choice
Twelve problems each run, drawn at random from a pool of 48 spanning the whole unit,
unlabeled — figuring out
what each one is even asking is half the skill. One attempt each; miss it and you get the full reasoning.
