IGCSE 2026 Exam Trends: Edexcel Mathematics B 4MB1

Edexcel IGCSE Mathematics B (4MB1) uses Paper 1 (non-calculator) and Paper 2 (calculator). It has a different emphasis from 4MA1 (e.g. more pure algebra/geometry). Here are recent trends for 2026.

Paper format and structure

• 4MB1 has Paper 1 (non-calculator) and Paper 2 (calculator); structure unchanged for 2025–2026.
• Non-calculator tests arithmetic, algebra (manipulation, solving), basic geometry; calculator includes trigonometry, graphs, statistics, constructions. Working is required; method marks are awarded.
• Formula sheet provided for Paper 2; correct use of formulae and rounding as specified are expected.

Question types and topics that keep coming up

• Algebra: Manipulation, changing the subject, quadratics, sequences; steps must be shown. Inequalities and simultaneous equations appear regularly.
• Geometry: Circle theorems, angles, constructions (loci, bisectors); construction arcs and accuracy are credited.
• Trigonometry: Right-angled and sine/cosine rules; bearings and triangles in context; use of formula sheet.
• Statistics: Cumulative frequency, box plots, probability (tree diagrams); interpretation and short “comment” answers.
• Number and graphs: Ratio, percentages, standard form; graph drawing and interpretation (linear, quadratic); axes and scale must be correct.

Are papers getting easier or harder?

• Standards are maintained via grade boundaries. Reports cite non-calculator fluency, multi-step reasoning, and omission of working as common issues.
• No reported shift in difficulty; clarity of working and following instructions (rounding, units) are key.

Similarity to past papers and predictability

• Format matches past Edexcel series. Past papers are a good guide to style and command words.
• Topics are predictable from the spec; exact questions are not. Method and presentation expectations are consistent.

Examiner expectations and marking

• Method marks for correct reasoning; “show that” needs all steps. Units and rounding as per question.
• Constructions and graphs: method and accuracy; arcs and labels required. Marking consistent with past series.

Assessment style and skills in demand

• Non-calculator fluency (fractions, percentages, algebra) and calculator application (trig, stats, graphs).
• Reasoning and application in context; multi-step problems.

Focus areas for 2026 revision

1. Non-calculator – practise arithmetic, algebra, simple geometry under time pressure.
2. Full working – every step for “show that” and calculations.
3. Constructions and graphs – arcs, labelled axes, neat diagrams.
4. Command words and rounding – “hence”, “to 2 d.p.”, “3 s.f.”.
5. Past papers – both papers under timed conditions.
