01 — Exam structure

Before you start, understand how the College Board scores.

AP Calculus BC has a balanced structure between MCQ (45 questions) and FRQ (6 questions) — each section accounts for 50% of the score. The structure mirrors Calculus AB but is harder because of 4 additional units (Series, Parametric, Polar). Understanding the structure helps your child allocate time to the right priorities.

2024 distribution of score 5/5

According to College Board data, up to 34.3% of students worldwide score a 5 in AP Calculus BC — the highest rate among AP Math subjects. Our students typically reach 60-70%+ score-5 thanks to a program drilling all 10 units and 6 FRQs to rubric standard.

Question 24 · MCQ Part A · No Calculator BC

Given the function f(x) = ∑(n=1 to ∞) (x − 2)ⁿ / (n · 3ⁿ). What is the radius of convergence of this power series?

  • AR = 1
  • BR = 2
  • CR = 3
  • DR = ∞

Solution: Apply the Ratio Test for the power series.

Consider L = lim |aₙ₊₁/aₙ| with aₙ = (x−2)ⁿ / (n·3ⁿ).

This gives L = |x−2|/3 · lim n/(n+1) = |x−2|/3.

The series converges when L < 1, i.e., |x−2| < 3Radius of convergence R = 3.

→ The correct answer is (C).

Schedule a consultation
On average 6-10 months (3 sessions/week, 90 min each) for students with a strong foundation. Our program covers 10 main CED units plus 4-6 mock exams before the May test. Students with a weaker foundation need an additional 2-3 months to build prerequisites before entering AP content.
The 2026 AP Calculus BC exam runs 3 hr 15 min in the College Board's official format. It includes 45 MCQ (multiple choice) and 6 FRQ (free response) questions. AP Calculus BC 2026 remains the traditional paper format. Our team will prepare your child for the answer-sheet process, calculator (graphing calc) use, and time management between Section I (45 MCQ in 105 min) and Section II (6 FRQ in 90 min).
It varies by school, but typically a 5 in Calculus BC = 3-8 credits at top 100 U.S. universities (saving roughly $4,000-$15,000 in tuition). Top schools like Harvard, Princeton, MIT often only accept a 5 and sometimes don't grant credit — but still use it for advanced placement into higher courses.
Our team uses a platform integrating an interactive whiteboard + screen-share, with every lesson recorded for review. Especially for Calculus BC — tutors can draw 3D graphs and write series formulas directly on the whiteboard. Students in Hanoi and HCMC can request in-person lessons at our offices when local tutors are available.
It's possible, if students have completed Pre-AP or equivalent foundation courses with A grades. Taking the AP early has upsides: it shows advanced standing on applications and leaves 2 more years for additional AP subjects. However, most students take Calculus BC in grade 11 or 12 for a more solid foundation.
Yes. Within the first 4 lessons, you or your child can request a tutor change free of charge if the teaching style doesn't fit. Our team will transfer all learning progress and assessments to the new tutor. After the 4th lesson, swapping incurs a small re-assessment fee.
