Unit
The essential chapter ideas in a clear sequence before practice.
Calculus studies how a quantity changes and how small changes accumulate. Graphical interpretation should accompany the notation.
Check domain, continuity, or differentiability where required. A correct rule cannot be applied mechanically outside its conditions.
A derivative represents local rate of change and a definite integral represents net accumulation. Always reconnect the result to the original problem.
Use a suitable representation, state the rule, and keep every numerical or algebraic step equivalent. Finish with estimation, an inverse operation, or substitution as a check.

Mathematics
Follow the method step by step and check why every step is valid.
For f(x) = x³ - 2x, find the derivative and the gradient at x = 6.
f'(x) = 3x² - 2, f'(6) = 106
Before calculating, explain the key idea from “AA: proof, exact algebra, analytical calculus, trigonometric identities” and which conditions must be checked.
The answer should show not only which rule is used for “AA: proof, exact algebra, analytical calculus, trigonometric identities”, but also why it is valid here.
Route emphasis
Eight graded tasks from core fluency to exam-style application. Work independently before opening a hint or answer.
For f(x)=x²+8x, find f'(x).
Use the power rule term by term.
f'(x)=2x+8.
Find the gradient of f(x)=x²+4x at x=2.
Differentiate, then substitute.
f'(2)=2·2+4=8.
Find ∫(7x+4)dx.
Increase the power by 1 and divide by the new power.
3.5x²+4x+C.
Evaluate ∫₀^6 3x dx.
Find an antiderivative and apply upper minus lower limit.
1.5·6² = 54.
Find the stationary point of f(x)=x²-6x+6.
Set f'(x)=0, then find y.
x=3, y=-3=-3.
If ds/dt=9t+5 and s(0)=14, find s(t).
Integrate and use the initial condition.
s(t)=4.5t²+5t+14.
Check whether F(x)=2.5x²+2x is an antiderivative of f(x)=5x+2.
Differentiate F.
F'(x)=5x+2=f(x), so yes.
A learner writes d(x³)/dx=3x. Correct it and explain the rule.
The power rule reduces the exponent by 1.
d(x³)/dx=3x².

Mathematics
Start from the board specification and work topic by topic before full papers.
The structure follows the official textbook layout and is used to organise study.
The areas that usually create mistakes or need extra revision.
Where to start: textbook, daily material, PDFs, videos, and worked examples.
Targeted practice before full tests so coverage is clear.
How to measure progress in this chapter and when it enters a cumulative mock.
What to do after finishing the chapter and how it connects to the next unit.
Note: for the official examinable syllabus of each school year, always confirm with the school, tutor, and current Ministry/IEP announcements.
