GGCSE tutoring
- One GCSE question
A wrong answer can look careless. Often, there is a missing idea underneath it.
A coat costs £60 in a sale after 20% off. What was the original price?
What your child wrote
Add the 20 per cent back on.
60 × 1.2 = £72
Not correct yet
Adding 20% to £60 feels like a sensible first step. But £60 is already the sale price. After 20% off, it represents 80% of the original price.A mark tells your child that the answer is wrong. A clear explanation helps them see why, so they can use the method on the next GCSE maths question.
What Kodori does
First, work out what the percentage refers to.
The difficult part is not the calculation. It is knowing which number represents the whole amount. Once your child understands that £60 is 80% of the original price, the calculation makes more sense.
1
Identify £60 as the sale price
2
Recognise that 20% off means 80% is left
3
Write: 0.8 × original price = £60
4
Find the original price, then try a similar question independently
This is the difference between a mark and an explanation.
Giving your child £75 gives them an answer. Helping them see that £60 represents 80% gives them a method they can use again in reverse percentage questions.

- Exam boards
AQA, Edexcel and OCR GCSE maths.
GCSE maths has common subject content in England, but AQA, Pearson Edexcel and OCR each publish their own specification and exam papers.
Kodori focuses on the mathematical idea behind the question. Your child does not need to choose an exam board before getting help with an available topic.For final exam preparation, use your school’s current specification and official past papers alongside Kodori.
- Where GCSE maths fits
GCSE maths often depends on earlier maths.
Kodori covers children aged 7 to 16, in Years 3 to 11, across KS2, KS3 and GCSE. That matters more at GCSE than anywhere else.
A difficult GCSE question can rely on an idea first taught years earlier. For example, a child struggling to rearrange an equation may need to revisit inverse operations before the GCSE method makes sense.Kodori can use a simpler example to rebuild that idea, then return to the GCSE maths question.

- FAQs
Questions parents ask about GCSE maths revision.
More questions are answered on the Kodori FAQ page.
Does Kodori cover AQA, Edexcel and OCR GCSE maths?
Yes. All three boards teach the same GCSE maths subject content, set by the Department for Education, so Kodori’s GCSE maths is written to that content and works whichever board your child’s school uses.
What differs between boards is how they assess it: paper structure, how marks are weighted, and some optional content. Kodori teaches and practises the maths itself.
Does Kodori cover Foundation and Higher GCSE maths?
Kodori supports Foundation and Higher GCSE maths topics currently available in the product. If you are unsure which tier your child is taking, their school can confirm it.
Will Kodori do my child’s GCSE maths revision for them?

My child understands GCSE maths in class but forgets it at home. Can Kodori help?
Yes. Your child can ask for the idea to be explained in a different way, use a simpler example and then try a similar GCSE maths question. This can help them reconnect the lesson with their homework or revision.
What year groups and subjects does Kodori cover?
Children aged 7 to 16, in Years 3 to 11, covering KS2, KS3 and GCSE in maths, English and science. GCSE maths is Years 10 and 11, ages 14 to 16.
