Parents often type "why is OCR maths so hard" after a mock. The usual answer they get is "OCR is just harder." That is not a useful diagnosis.

Edexcel 1MA1 and OCR J560 cover the same GCSE maths content: number, algebra, ratio, geometry, probability, and statistics. Both use three papers. Both last 1 hour 30 minutes. Paper 1 is non-calculator. Papers 2 and 3 allow a calculator.

The difference that shows up in the hall is the mark total.

The core difference: 80 marks vs 100 marks in the same 90 minutes

Edexcel 1MA1 is three papers of 80 marks. OCR J560 is three papers of 100 marks.

Do the arithmetic. Edexcel gives you about 67 seconds per mark. OCR gives you 54 seconds per mark. That is not a small style difference. It is a different exam.

On OCR, students who "know the topic" still bleed marks in the final third of the paper. They spend too long on a 3-mark algebra item, then rush a 6-mark multi-step question they could have scored on. The paper is long enough that concentration drops. The last 20 marks are where grade 6s become grade 5s.

On Edexcel, the clock is slightly kinder per mark, but the last questions on Higher papers 2 and 3 are built as chains. One question can pull together ratio, algebra, and a graph. Students who skip working lose method marks that Pearson still awards if the chain is shown.

If you want board-specific teaching rather than generic GCSE maths, start with Edexcel 1MA1 problem-solving experts or specialist OCR J560 Maths tutors.

What that means for pacing

A student who revises from mixed-board worksheets will not learn this. An 80-mark Edexcel paper and a 100-mark OCR paper feel different even when the topics match.

For OCR J560 we train a time-per-mark habit early:

• Glance at the remaining marks every 20 minutes, not only at the end.
• Leave a 4-mark "stuck" question after two minutes and come back.
• Protect the last 15 minutes for the high-mark items, even if that means skipping a messy 2-mark arithmetic slip.

For Edexcel 1MA1 the drill is different:

• Write every step. Pearson's mark schemes pay for method.
• Practise the final five Higher questions as a set, not as one-off puzzles.
• Treat "show that" and multi-step ratio items as a format, not as surprise difficulty.

Same student. Same topics. Two different exam crafts.

The Foundation vs Higher trap

Both boards cap Foundation at grade 5 and open Higher from grade 4 to 9. Families often push Higher because "grade 6 keeps options open." That is only true if the student can finish a Higher paper without collapsing in the last 20 marks.

Our rule of thumb, taken from the practice papers we actually sit with students: recommend Higher only if they are consistently scoring above 55 to 60 percent on Higher papers. Consistently means several papers, not one lucky mock.

Below that line, Foundation is not a demotion. It is the paper that still awards a 4 or 5 without asking the student to outlast a 100-mark OCR Higher or an Edexcel multi-step finale they cannot yet structure.

OCR makes this call sharper. The Higher papers are long and problem-heavy at the top end. A student at 48 percent on Higher OCR is usually safer on Foundation, then rebuilt, than left to "see how Higher goes in June."

Edexcel's trap is the opposite shape. Students scrape 58 percent on Higher because method marks keep them afloat, then freeze on the last unstructured questions. They need problem-solving chains, not more topic notes.

Where students actually lose the grade

We see the same three failure points on both boards. The fix is not the same.

Running out of time. This is the OCR signature. A 90-minute, 100-mark paper punishes slow starters. Timed 100-mark practice is not optional. Topic booklets will not show you this.

Blank last questions. This is the Edexcel Higher signature. The student can expand brackets and solve a quadratic in isolation, then cannot chain them inside a worded context. Drill the chain, not the skill in isolation.

Skipping working. Both boards, worse on Edexcel. A correct answer with no method can still drop marks. An incomplete method can still pick some up.

If you are not sure which of those three is your child's problem, a mixed "GCSE maths tutor" will guess. A board tutor should be able to tell you after one timed paper.

How StudyHours diagnoses this

We do not start with a scheme of work copied from Year 11. After a free trial lesson, the teaching run uses a three-session diagnostic.

Session 1: the diagnostic. The student sits board-true material. For OCR that includes a timed slice of a 100-mark paper so we can see where the clock breaks. For Edexcel we watch whether they can start a multi-step item and keep the working complete. We are looking for why they miss marks, not only which topic title is weak.

Session 2: targeted repair. If the issue is OCR pacing, we rebuild time-per-mark and finishing drills. If the issue is Edexcel chains, we teach the pattern of those last questions. We do not spend the hour on a topic they already score on.

Session 3: progress review and an 8-week map. You get a written plan tied to the actual specification code, J560 or 1MA1, and a tier recommendation based on the papers they sat, not a hunch.

The free offer is the trial lesson. The three-session sequence is how the tutoring is structured once you continue.

What to do this week

1. Confirm the board. Look at a recent paper or the school exam handbook. J560 is OCR. 1MA1 is Edexcel. AQA is a third structure again.
2. Sit one past paper under exam timing. Do not pause. Do not "finish it later."
3. Mark it with the official scheme, including method marks.
4. Decide tier with the 55 to 60 percent Higher rule, not with what a friend is sitting.

If the paper is OCR and the last 20 marks are blank, you have a pacing problem. If the paper is Edexcel and the last questions are blank but the earlier algebra is fine, you have a problem-solving format problem.

Those are teachable. They are not a sign that "OCR is impossible" or "Edexcel is unfair."

Not sure which board your child is on, or what tier they should sit? Book a free trial lesson and we will build a pacing plan from a real paper.

FAQ

How many marks are OCR J560 maths papers compared with Edexcel 1MA1?

OCR J560 sets three papers of 100 marks each. Edexcel 1MA1 sets three papers of 80 marks each. Both boards give 1 hour 30 minutes per paper.

Is OCR maths harder than Edexcel?

Content is close. OCR is harder on stamina because 100 marks sit in the same 90 minutes. Edexcel Higher is harder on unstructured multi-step questions at the end of the paper.

Should my child sit Higher or Foundation?

Higher only if they are consistently above 55 to 60 percent on Higher practice papers. If you need a secure 4 or 5, Foundation is often the better paper.
