Mixed multiple choice across all of Unit 4 — interpreting rates in context, straight-line motion,
related rates, linear approximation, and L’Hôpital’s rule — plus a free-response trainer built on
real AP question shapes. Every answer is worked and verified, and every wrong option is a mistake worth knowing.
How to use this. The multiple choice pulls a fresh batch of 12 from a bank of 50, mixing every topic and both
exam sections — each question is tagged calculator or no calculator, the way the real test splits them.
Answer, read the worked explanation, and your weak spots surface at the bottom. Then train the free-response
format — one scenario, several chained parts — exactly how Section II works.
