Our Approach

How We Help You Score a 5

Conceptual Depth

We teach calculus as a connected framework, not isolated procedures. Understanding the Fundamental Theorem deeply changes everything.

FRQ Writing Skills

We train you to write FRQ responses the way the College Board wants. Proper justification is the difference between a 4 and a 5.

Calculator Strategy

Knowing when and how to use your calculator saves critical time. We drill efficient calculator techniques for both sections.

AP-Style Practice

We use real AP past exam questions exclusively. No generic worksheets. You practise exactly what you will face.

AP Calculus AB & BC Syllabus

What You'll Learn

→

Limits & Continuity

Limit definition, limit laws, squeeze theorem, continuity, and the Intermediate Value Theorem. The conceptual foundation of calculus.

∂

Differentiation

Definition of derivative, differentiation rules (power, product, quotient, chain), implicit differentiation, and related rates.

📐

Applications of Derivatives

Mean Value Theorem, curve sketching, optimisation, linearisation, and L'Hopital's rule.

∫

Integration

Riemann sums, Fundamental Theorem of Calculus, u-substitution, integration by parts (BC), and partial fractions (BC).

📊

Applications of Integration

Area between curves, volumes of revolution (disc, washer, shell), and accumulation functions.

∞

Series (BC Only)

Convergence tests, Taylor and Maclaurin series, power series, radius and interval of convergence, and error bounds.

How the exam works

AP Calculus Exam Format

The AP exam tests both computational skill and conceptual understanding across two sections.

Exam length

3 hours 15 minutes (AB and BC)

Score weighting

50% Section I (MCQ) · 50% Section II (FRQ)

Section I

45 multiple-choice questions

Section II

6 free-response questions

Section I — Multiple choice

Breadth across all course units; calculator policy flips halfway through the block.

Part A

30 questions

No calculator · 60 minutes

Part B

15 questions

Graphing calculator · 45 minutes

On the exam

AB and BC share timing; BC items reach further into series, polar, and vector content where applicable.
Stem style rewards steady recognition — we map recurring College Board patterns so revision time compounds.
Pacing: Part A rewards clean algebra; Part B rewards efficient calculator routes without losing structure.

With us: We drill unit-by-unit weak types, then fuse under full Section I timing so the calculator handoff at Part B never costs cold minutes.

Section II — Free response

Half of your score — written reasoning, justification, and communication are scored explicitly.

Part A

2 questions

Calculator required · 30 minutes

Part B

4 questions

No calculator · 60 minutes

On the exam

Examiners reward complete justification: setup, intermediate reasoning, and linked conclusions — not answer-only drops.
Part B without calculator tests algebraic fluency on integrals, limits, and series-style structure (BC).
Typical mix includes modelling, accumulation, area/volume, and reasoning with tables or verbal stems.

With us: FRQ work is scored like the rubric: we rehearse standard proof phrases, variable hygiene, and time-boxing per question so a 5 remains in reach under pressure.
