Most parents never see inside a GCSE Maths mark scheme — but these documents quietly control every single mark your child earns. Once you understand them, you’ll be able to guide your child more effectively than 90% of students.

1. Marks Are Not Just About “Getting It Right”

GCSE Maths awards marks for:

Method
Reasoning
Accuracy

This means a student can earn half or more of the marks even if their final answer is wrong — if they show their working logically.

2. Why Students Lose Easy Marks

From tutoring many of students, the most common reasons for lost marks are:

Not showing an essential step
Rounding early
Using incorrect units
Writing an unexplained answer
Skipping method on a calculator question
Not using the correct mathematical notation

These are not “ability problems” — they’re technique problems, and they are fixable.

3. Grade 4–5 Students Often Need “Exam Discipline”, Not Extra Content

Many parents think their child needs to learn more maths. Often, they simply need to follow exam-friendly habits consistently.

For example:

Always underline key words
Box the final answer
Show steps even when using a calculator
Write a short sentence on reasoning questions

Small habits = large grade jumps.

4. Teach Your Child to “Mark Like an Examiner”

A game-changing strategy:

Take a past paper.
Your child marks their own work using the official mark scheme.
They highlight exactly why each mark was lost.
They re-do the question correctly.

This builds exam awareness fast.

5. Why This Matters for Parents

Once you know how marks are awarded, you can:

Spot where your child is losing marks
Support their revision more effectively
Help them practise the right way
Stop arguments based on guessing or frustration

Maths becomes less emotional and more objective.
