You normally need roughly 40–65% of the marks on GCSE Maths Foundation to “pass” with a grade 4 , but the exact number of marks changes every year and depends on the exam board (Edexcel, AQA, OCR, etc.).

How many marks to pass GCSE Maths Foundation?

The simple version

  • A grade 4 is the standard pass in GCSE Maths.
  • On Foundation tier , that has recently worked out to about 135–160 marks out of 240 (roughly 56–67%).
  • Because the papers change in difficulty, grade boundaries move slightly every year , so there is no single fixed mark.

Think of it like this: if you’re consistently scoring over half the total marks on recent past papers for your exam board, you’re moving into realistic grade 4 territory.

Recent example numbers (to give you a feel)

These are typical recent ranges , not guarantees:

  • Edexcel Foundation : around 144–147 marks out of 240 has been enough for a grade 4 in recent series.
  • AQA Foundation : around 135–160 marks out of 240 for a grade 4 , depending on the year.
  • In percentage terms, that’s usually somewhere between the mid‑50s and mid‑60s percent.

So if each paper is marked out of 80 , a rough guide is that you often need about 45–55 marks per paper on average to be in the grade‑4 zone, though it can be a bit lower or higher depending on the year.

Why it changes every year

Exam boards set grade boundaries after they see how hard the paper turned out to be.

  • If the exam is harder than usual , you may need fewer marks to get a 4.
  • If the exam is easier , the boundary can go up.
  • Boundaries also differ between boards — AQA’s numbers won’t match Edexcel’s exactly.

That’s why you’ll always see wording like “typically around 40–60%” for a pass.

What you should do in practice

  1. Check your exam board.
    Look up the official grade boundaries for your board (Edexcel, AQA, OCR) from last year’s Foundation Maths papers.
  1. Use past papers as your guide.
    • Do full past papers in timed conditions.
    • Mark them using the official mark schemes.
    • Compare your total marks to last year’s grade‑4 boundary for that board.
  1. Aim above the bare minimum.
    Because boundaries move, try to be comfortably above the last known grade‑4 mark – e.g. if last year’s 4 was ~140/240, aim for 150–160+ in practice.

If you’re close to the boundary

Students often miss a pass by just a few marks across all three papers – which is why people sometimes consider a remark if they’re very close.

The good news is that small improvements in method marks, showing working, and checking for silly mistakes can be enough to tip you over the line into a 4. TL;DR:
There isn’t one fixed mark, but for GCSE Maths Foundation you usually need around 135–160 marks out of 240 (about 40–65%) for a grade 4 pass , and the exact boundary depends on the year and exam board.
