Rational functions, asymptotes, reciprocal, modulus functions
Factor theorem, remainder theorem, polynomial division, roots
Complex roots, sum and product, partial fractions, HL extensions
Direct proof, proof by contradiction, mathematical induction
Strong induction, disproof by counterexample, HL proof extensions
Unit circle, exact values, identities, equations, transformations
Compound angles, double angle, R-form, modelling, HL identities
Cartesian, polar, exponential forms, De Moivre's theorem, roots
2D and 3D vectors, dot product, cross product, equations of lines
Coordinate geometry, circle equations, intersections, proofs
Planes, intersections, distances, angles between planes and lines
Limits, derivatives, rules, implicit differentiation, related rates
Antiderivatives, definite integrals, area, volume, integration techniques
Taylor and Maclaurin series, interval of convergence, HL applications
Separation of variables, Euler's method, slope fields, HL extensions
Most IB resources are built backwards from mark schemes. This one is built forwards from mathematical principles.
One purchase includes all seven components — no add-ons, no separate purchases.
Complete written course across all 27 AA HL chapters — R. Chadha Signature Model with Thinking Framework boxes, fully reasoned worked examples, and layered practice sets.
27 Chapters · 1000+ Solved · 1250+ Practice ProblemsEvery topic covered on video — concept by concept. Not recorded lectures but carefully structured lessons built specifically for IB AA HL and SL.
Complete Syllabus CoverageExamination-style questions mapped to every topic and difficulty tier — Section A, B, and C. Builds genuine examination readiness, not question recognition.
1,500 Questions · All Difficulty TiersDedicated preparation for the HL extension paper — problem-solving approach, multi-concept reasoning, and worked examples at Paper 3 standard.
HL Paper 3 · Problem-Solving ApproachThe Internal Assessment prepared as a piece of mathematical writing — not a school project. Topic selection, mathematical development, and presentation at a mathematician's standard.
IA Strategy · Mathematical Depth · ExplorationDedicated video sections for Paper 3 walkthrough, IA methodology, and GDC usage — the three areas where focused video guidance makes the biggest difference to final grade.
Paper 3 · IA Guidance · GDC MasteryPrevious IB examination papers with worked solutions and examiner-perspective commentary — connecting each question back to its underlying mathematical concept.
Previous Years · Worked Solutions · CommentaryThe pedagogical architecture behind all 10 of Dr. Chadha's advanced mathematics textbooks. Applied to every chapter of IB AA HL.
Every chapter opens with a gap diagnosis before new content begins
The mathematical idea stated clearly — before any formula appears
Precise mathematical language — the standard a university would use
Why the result is true — not given, proven from first principles
The reasoning pattern for this concept — transferable, not memorised
Foundation examples — concept meets calculation, fully annotated
Examination-standard — the level the IB actually tests
HL Synthesis — multi-concept, Paper 3-style problems
The mistakes examiners see most — named, explained, corrected
Calculator technique where relevant — when to use, when not to
Skill-building — fluency with the core technique
Examination practice — IB-style questions, full range of difficulty
HL Synthesis — multi-topic questions requiring Paper 3 reasoning
Investigation starting points with genuine mathematical depth
