AP Calculus AB
AP Calculus AB is roughly equivalent to a first-semester college calculus course. It covers limits, derivatives, integrals, and the Fundamental Theorem of Calculus with a focus on conceptual understanding and applying these tools to real-world problems.

Study Tips
- 1
Master the derivative rules (power, product, quotient, chain) before anything else — they underpin nearly every problem.
- 2
Understand the Fundamental Theorem of Calculus conceptually: it links derivatives and integrals.
- 3
Practice free-response under timed conditions every week leading up to the exam.
- 4
Learn to read and interpret graphical information — many questions give a graph of f and ask about f' or ∫f.
- 5
Know your calculator well: store functions, find intersections, compute numerical derivatives and integrals.
Past Exam Questions
Let f(x) = x³ − 3x² + 2. Find all intervals on which f is increasing, all local extrema, and the absolute maximum on [0, 3].
A particle moves along the x-axis with velocity v(t) = t² − 4t + 3 for t ≥ 0. Find the total distance traveled from t = 0 to t = 4, and determine whether the particle is moving left or right at t = 3.
Common Mistakes to Avoid
- ✕
Skipping steps in working, which throws away method marks when the final answer is wrong.
- ✕
Not sanity-checking answers for reasonableness (wrong units, impossible magnitudes, extraneous solutions).
- ✕
Dropping negative signs and misapplying the order of operations under time pressure.
