What is Differential Equations?
Differential Equations belongs to Core Pure in A-Level Further Mathematics. The reliable way to revise it is to learn the trigger condition, write the first method line clearly, and practise enough variations that you can spot when the standard method needs adapting. For Further Maths, pay special attention to proof, notation, and whether a result follows from earlier parts of the question.
Board notes: AQA, Edexcel and OCR differ in wording and calculator/non-calculator balance. Use this as a method lesson, then check your board specification and past-paper style for exact demand.
Step-by-step explanationWorked examples
Worked example
For a Differential Equations question, first classify the problem: what information is given, what form should the answer take, and which rule from Core Pure applies? Write the method line, carry out each transformation cleanly, then substitute or check the result against the original condition. This creates a mark-scheme-friendly answer even when the arithmetic is demanding.
Practise this topic
Start with low-focus cards for Differential Equations, then move into full exam-style practice when you want the heavier session.
Targeted practice plan
- 1Attempt one standard Differential Equations problem and annotate every theorem, identity, or earlier result you use.
- 2Attempt one harder Core Pure problem where the first method is not obvious; write two possible routes before solving.
- 3After marking, rewrite the solution in the fewest rigorous steps that still justify every transition.
Common mistakes
- 1Starting calculations before identifying the exact form of the question.
- 2Skipping algebraic or numerical working that the mark scheme would credit.
- 3Not checking whether the final answer needs units, exact form, a diagram interpretation, or a stated conclusion.

Frequently asked questions
How do I get better at Differential Equations?
Practise in short sets: one easy recognition question, one standard method question, and one mixed question. After each attempt, mark the first line and the final check separately.
What loses marks in Differential Equations?
Most lost marks come from wrong method selection, missing intermediate steps, or an answer that is mathematically correct but not in the requested form.
