Change and approximation
Calculus studies how a quantity changes and how small changes accumulate. Graphical interpretation should accompany the notation.

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.
Mathematics
Follow the method step by step and check why every step is valid.
For f(x) = x³ - 3x, find the derivative and the gradient at x = 7.
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.
f'(x) = 3x² - 3, f'(7) = 144
Before calculating, explain the key idea from “Probability distributions” and which conditions must be checked.
The answer should show not only which rule is used for “Probability distributions”, but also why it is valid here.
Statistics, probability and calculus synthesis
Try independently, use the hint if needed, then open the answer guide.
1. Explain the idea and give one correct foundation example for “Probability distributions”.
Write the givens, a useful representation or rule, and only then calculate.
A complete answer defines “Probability distributions”, shows equivalent steps, and includes a final check.
2. Solve an application and show every intermediate step for “Statistical testing”.
Write the givens, a useful representation or rule, and only then calculate.
A complete answer defines “Statistical testing”, shows equivalent steps, and includes a final check.
3. Compare a correct and an incorrect approach and justify the difference for “Optimisation”.
Write the givens, a useful representation or rule, and only then calculate.
A complete answer defines “Optimisation”, shows equivalent steps, and includes a final check.
4. Create a short exam-style question and check your answer for “Area and accumulation”.
Write the givens, a useful representation or rule, and only then calculate.
A complete answer defines “Area and accumulation”, shows equivalent steps, and includes a final check.
Where to start: textbook, daily material, PDFs, videos, and worked examples.
Targeted practice before full tests so coverage is clear.
