A report card lands on the kitchen table with a row of numbers, and a parent wonders whether a 6 is a relief or a worry. A student switching from ICSE percentages or a school's internal marks may not know whether a 5 in one subject is worth celebrating. Confusion about the scale is common, and it can quietly shape how a child feels about a subject before any real work has begun.
The short answer: Cambridge IGCSE uses a 9 to 1 scale for most subjects, where 9 is the highest, and 4 is a standard pass. Some subjects and older syllabuses still report A* to G, where A* is the top grade. Once you know where the pass lines sit on each scale, the numbers become a plan rather than a verdict.
Why a 7 and an A can mean the same thing
The 9 to 1 scale replaced letter grades in many IGCSE subjects. It is not a simple ten-point percentage. Each number marks a grade boundary set by the examiners, so a 7 tells you that a candidate reached a particular standard, not that they scored 70 per cent. Cambridge publishes the approximate link between the two systems: grade 9 sits near A*, grade 7 near A, grade 4 near C and grade 1 near G. Treat these as broad equivalents rather than exact conversions, because the boundaries are set syllabus by syllabus.
Two numbers matter most for most families. Cambridge describes grade 4 as a standard pass and grade 5 as a strong pass. Many schools, colleges and sixth forms look for a 4 or 5 in English and Mathematics, so those two grades are worth watching closely.
Reading a report without panicking
When you see a mix of scales on one report, check three things before reacting:
- Which scale is in use. The label or the syllabus code usually tells you whether the subject uses 9 to 1 or A* to G.
- Whether the grade is a mock or a final result. Mock grades are practice signals. They are meant to show gaps, so a low mock is information, not a final judgement.
- Which topics pulled the mark down. A grade rarely fails because of everything. It usually dips because of one or two papers, one command term the student keeps misreading, or a section of the syllabus that was rushed.
A calm conversation about those three points does more good than comparing the number with a sibling's or a friend's.
Turning grades into a revision plan
The grade tells you where the student stands. The mark scheme tells you what would move them up. Ask the teacher for the last mock's mark scheme and check which answers earned the marks. Students often lose marks not because they lack knowledge, but because they answer a different question from the one set: they explain when the command term asks for evaluation, or they name a process without giving the detail the scheme rewards.
A simple routine helps. Each week, pick one past paper section, mark it against the scheme, and write down three specific errors. Then practise only those errors for the next few days. This is slower than rereading notes, but it is the habit that moves a grade 5 towards a 6 or 7.
Working in a small group can make this easier, because a teacher can spot the same error across several students and address it once. At INACADEMICS, our IGCSE teaching is built around this approach: classes of four to eight students, specialist teachers who work from IGCSE mark schemes and past papers, a short diagnostic at the start, and monthly mocks followed by a clear update for parents. You can read more about our Cambridge IGCSE tuition for Grades 9 and 10.
Choosing support that fits the scale your child is working on
Whatever tuition you consider, ask how the teacher uses the grading. A good answer will mention the mark scheme and the grade boundaries, not only the number of hours or the reputation of the centre. Ask how progress is measured, how often you will hear about it, and whether the plan changes if the first mock goes poorly. Families who ask these questions tend to find the right fit more quickly than those who choose on price or proximity alone.

Frequently Asked Questions
Is a grade 4 in IGCSE a pass?
Yes. Cambridge describes grade 4 as a standard pass and grade 5 as a strong pass on the 9 to 1 scale. Many post-16 courses and employers look for at least a 4 in English and Mathematics. If your child is aiming for a particular sixth form, check its entry requirements early, because they can differ.
How do IGCSE grades 9-1 compare with A* to G?
Broadly, grade 9 sits near A*, grade 7 near A, grade 4 near C and grade 1 near G. The mapping is approximate, and boundaries vary by subject. Your child's school or exam board report will show which scale applies to each subject.
What if my child's mock grade is lower than expected?
A low mock is useful information. At INACADEMICS, we start with a diagnostic and a per-subject plan, then review each monthly mock against the mark scheme so we can see which skills need attention. We share those findings with parents, so the next steps are clear rather than guessed.
