How should I revise algebra for GCSE Maths?

Revise algebra by building confidence with one skill at a time, then mixing those skills together in exam-style questions.

Check the foundations first

Make sure you can confidently:

• simplify expressions
• expand and factorise brackets
• solve linear equations
• substitute values into formulae
• rearrange simple formulae

If one step feels uncertain, practise that skill before moving to longer questions.

Follow a repeatable method

1. Read one worked example.
2. Cover the solution and repeat it yourself.
3. Complete five similar questions.
4. Mark them immediately.
5. Correct every error in a different colour.

Example

To solve $3x+7=22$, subtract 7 from both sides and then divide by 3:

$$3x=15$$ $$x=5$$

Always substitute your answer back into the original equation when you have time. It is a quick way to catch sign and arithmetic errors.

Once individual skills feel secure, use mixed questions so you must decide which method to apply without being told.
