Calculus and Trigonometry: The Big Two of 0606

If a student could only master two 0606 topics, these are the two: calculus and trigonometry. They are the largest topics in the syllabus, they appear heavily on both papers every session, and, crucially, they are method-heavy, so they respond to drilling more reliably than almost anything else. Get strong in these two and a large share of the paper is secured before you touch the rest.
What to expect from calculus
Calculus spans more distinct skills than any other 0606 topic, and a paper typically samples several of them:
- Differentiation using the product, quotient and chain rules, often as a first step into a bigger question.
- Stationary points, find, classify with the second derivative, conclude, examined in almost every session.
- Tangents and normals, straightforward marks once the routine is clean.
- Integration and area, including the below-the-axis modulus trap.
- Kinematics and connected rates, the applied layer students find hardest, and the most trainable.
The applied questions (rates, optimisation) are where students freeze, and precisely where drilling the fixed routine turns panic into reliable marks.
What to expect from trigonometry
Trigonometry is the second big mark source and rotates through a predictable set:
- Identity proofs, work one side down using .
- Solving equations, often a hidden quadratic, in a given range.
- Exact values and graphs, amplitude, period, transformations.
Every one of these is a routine. The identity proof that looks impossible is mechanical once you know to start from the busy side; the equation you cannot solve is usually a hidden quadratic waiting to be factorised.
Why they reward drilling most
Both topics share a feature that makes them the highest-return revision: the question types repeat. The same stationary-point recipe, the same identity routine, session after session. That means practice compounds, drilling ten past-paper calculus questions genuinely prepares you for the eleventh, in a way that is less true of more open-ended subjects. This is the deeper reason Add Math difficulty responds to method rather than talent.
Make these two your strongest areas and the rest of the paper feels lighter. A specialist can identify which specific routines within calculus and trig your child hasn’t yet locked in, and drill them fast, that is what the trial class diagnoses. Message us on WhatsApp to book.
