AP Calculus AB / BC Drilling Guide: Section I and Section II, Order and Pacing
TUTORZONE EXAM DRILL GUIDE · AP CALCULUS AB / BC
AP Calculus has an institutional constraint: a candidate may not sit both AB and BC in the same year. The exam runs 3 hours 10 minutes: 42 multiple-choice questions worth 50% (Part A 29 questions with no graphing calculator, Part B 13 with calculator for some) and six free-response questions worth 50% (Part A 2 problems with calculator, Part B 4 without). Which sections allow a calculator is itself the basis of your drill allocation.
How is the AP Calculus exam structured?
Direct answer: the exam lasts 3 hours 10 minutes in two sections. Section I: 42 multiple-choice questions, 1 hour 40 minutes, 50% – Part A 29 questions with no graphing calculator (35%) and Part B 13 questions with a calculator required for some (15%). Section II: 6 free-response questions, 1 hour 30 minutes, 50% – Part A 2 problems with the calculator (16.7%) and Part B 4 without (33.3%). Multiple choice is answered in the Bluebook app and free response is handwritten in the exam booklet.
Assessment at a glance (2027)
| Component | Content | Weighting | Duration |
|---|---|---|---|
| Section I · Part A (MC, no graphing calculator) | 29 questions, 35% of the score; algebraic, exponential, logarithmic, trigonometric and general functions in analytical, graphical, tabular and verbal forms | 35% | (Section I: 1 h 40 min total) |
| Section I · Part B (MC, calculator for some) | 13 questions, 15% of the score | 15% | (as above) |
| Section II · Part A (free response, calculator required) | 2 problems, 16.7% of the score; questions shown in Bluebook and answered by hand in the exam booklet | 16.7% | (Section II: 1 h 30 min total) |
| Section II · Part B (free response, no calculator) | 4 problems, 33.3% of the score | 33.3% | (as above) |
AP Calculus is 3 hours 10 minutes with multiple-choice and free-response at 50% each. Note that the no-calculator sections together are 35% + 33.3%, about 68% of the score, so drilling should lean on hand and symbolic work.
What each paper is actually testing
| Paper | Drill focus | How marks are lost |
|---|---|---|
| Section I · Part A (MC, no graphing calculator) | Train calculator-free judgement: symbolic manipulation, limits, and the definitions of derivative and integral | Over-reliance on the calculator and weak symbolic work; a loose rhythm across 29 consecutive questions |
| Section I · Part B (MC, calculator for some) | Train calculator-assisted graph and numerical work: intersections, zeros, extrema, definite integrals | Unfamiliar with your own calculator routine, so time is lost exploring menus |
| Section II · Part A (free response, calculator required) | Train the explanation: not just the value, but full sentences stating the reason and the meaning | Answers with no explanation; units and context ignored |
| Section II · Part B (free response, no calculator) | Train handwritten solution writing and symbolic work; losses here come from not showing steps rather than not knowing | Omitted steps; failing to name the theorem or definition used |
Should you take AB or BC?
Direct answer: first, a candidate may not sit both AB and BC in the same year. BC adds further topics on top of AB (series, parametric and polar functions, vector-valued functions) and includes BC-only items; AB is narrower. Choose by your intended degree requirements and your current calculus base, not by popularity.
Drill order: by topic, then by year, then the mark scheme
| Step | What you do | Why |
|---|---|---|
| 1. By topic | Work through each topic, starting with the paper that allows least help (no calculator / closed book) | Exposes what is genuinely not understood |
| 2. By year | Whole papers to time, one or two a week | Trains pace, stamina and question selection |
| 3. Mark scheme | Go through the marking scheme question by question and log the scoring steps you missed | Most lost marks are written wrong, not thought wrong |
How should free-response answers be written?
Direct answer: the AP rubric splits each question into scoring points (usually nine per question), so answers are marked point by point: (1) name the theorem or definition used; (2) show the key steps, including the equation or integral you set up even when the calculator does the arithmetic; (3) explain the meaning of the result in context, in full sentences; (4) state the units. A bare final value earns very little.
A 12-week drilling timetable
| Week | Phase | What to do |
|---|---|---|
| Weeks 1-3 | By topic: foundation | Topic by topic, starting with the easiest marks, building habits and recall |
| Weeks 4-6 | By topic: core | 8-10 years of the same topic back to back, errors classified by topic |
| Weeks 7-8 | By topic: advanced and electives | Elective and higher-order topics, now under time pressure |
| Weeks 9-10 | By year: timed papers | One full paper a week, timed, no reference materials |
| Week 11 | Mark scheme work | Question by question against the marking scheme; list the scoring steps you omitted |
| Week 12 | Plug holes and simulate | Only the recurring errors from your log, then one full exam simulation |
Subject-specific weighting for this timetable: Give more than half of AP Calculus drilling to no-calculator work, with the rest split between calculator-assisted questions and free-response writing. Week 11 should be entirely devoted to writing explanations.
Use it properly: this is not a checklist to finish. Every week must keep time for redoing errors, or from week 9 you will be repeating the same batch.
Pacing
| Paper | Time | Suggested split |
|---|---|---|
| Section I · Part A (MC, no graphing calculator) | （Section I 共 1 小時 40 分鐘） | Section I totals 100 min; allow about 60 for Part A |
| Section I · Part B (MC, calculator for some) | （同上） | About 40 min |
| Section II · Part A (free response, calculator required) | 1 小時 30 分鐘（Section II 共） | About 30 min |
| Section II · Part B (free response, no calculator) | （同上） | About 60 min |
How should the no-calculator sections be prepared?
Direct answer: treat hand work as its own skill: derivatives and integrals of common functions, limit reasoning, symbolic manipulation and algebraic simplification. With about 68% of the score in no-calculator sections, more than half of your drilling should happen without the calculator, checking included.
The drilling mistakes that cost the most marks
| Mistake | What it looks like | What actually happens | Instead |
|---|---|---|---|
| Over-reliance on the calculator | Reaching for it first on every question | About 68% of the score is no-calculator, so the paper collapses | Drill more than half the time without it, checks included |
| Free response with answers only | Stopping at the value | AP marks point by point, so a bare value scores almost nothing | Theorem, steps, explanation, units – all four |
| Mixing AB and BC drilling | Covering both just in case | Both cannot be sat in one year, so the time is wasted | Fix AB or BC first and drill only that |
The error log and the mark scheme
File the AP Calculus log by scoring-point type: naming definitions and theorems, showing steps, contextual explanation, units. Because AP marks point by point, splitting losses this way shows that one or two types – not whole questions – are what you consistently miss.
How many years should you drill?
Eight to ten years of free-response questions covers the main types; multiple choice is not released, so drill by topic and time the latest five years of free-response papers.
How many years of AP Calculus questions should you drill?
Direct answer: no official figure, but the College Board publishes each year’s free-response questions, and the last eight to ten years covers the main question types. Multiple-choice items are not released, so drill by topic and question type, and sit the latest five years of free-response questions under timed conditions.
Frequently asked questions
Is AP Calculus a paper or digital exam?
Hybrid: multiple-choice questions are answered in the Bluebook app and free-response answers are handwritten in the exam booklet.
May I take AB and BC in the same year?
No. Candidates may not sit both AP Calculus AB and BC in the same year.
What is the calculator policy?
Some questions require an approved graphing calculator (Section I Part B and Section II Part A) and the rest prohibit it; check the College Board’s calculator policy for your exam year.
