IB Mathematics Revision

Q: Does OES provide official IB past papers?

No. OES does not redistribute official copyrighted past papers. Our AI generates fresh, IB-style practice papers and revision resources that mirror the structure, command words and difficulty of real IBO (International Baccalaureate Organization) exams.

Q: Is the Mathematics content aligned to the current IB specification?

Yes. Mathematics notes, flashcards and exam-style questions on OES are mapped to the current IB specification across IBO (International Baccalaureate Organization), so you are only revising what is actually on the paper.

Q: How does the AI mark my IB Mathematics answers?

Our AI marks your answers against published mark-scheme conventions, command word by command word. It tells you which mark points you hit, which you missed, and how to rephrase weak answers to pick up the extra marks.

Q: Is OES useful for top-grade IB students, or only for catching up?

Both. Strong IB students use OES to drill the highest-tariff questions and refine technique on extended responses. Students who are behind use it to rebuild gaps quickly with focused notes and adaptive flashcards.

Q: How is OES different from a generic AI chatbot for IB revision?

OES is built specifically for IBO (International Baccalaureate Organization) exam revision. Content is spec-aligned, marking is mark-scheme aware, and the personal AI Study Coach is trained on real exam-board conventions — not just general knowledge.

Q: How should I structure my IB Mathematics revision week to week?

Start by mapping your weakest Mathematics sub-topics, then alternate notes, flashcards and exam-style questions across the week. The AI Study Coach can build a weekly plan and adjust it as you improve. In the final 4–6 weeks, switch to full IB-style timed papers.

Q: Do I need to pay to use OES for IB?

OES has free tools to get started. Paid plans unlock unlimited IB-style exam papers, deeper AI feedback and the full Personal AI Study Coach experience.

Master IB Mathematics with AI tools built around the real specification — concise notes, adaptive flashcards and exam-style practice marked against published mark-scheme conventions.

Revise Mathematics on OES For Learning

IB Mathematics is a high-volume, high-stakes subject — number and algebra, functions and calculus, geometry, trigonometry and vectors, statistics, probability and modelling — and the gap between a strong grade and a top grade is rarely about how many hours you put in. It is about whether those hours target the spec points, command words and exam techniques that actually move marks on IB papers.

OES gives you concise spec-aligned notes for every Mathematics sub-topic, adaptive flashcards that prioritise what you keep forgetting, and AI-generated exam-style questions marked against the published IB mark-scheme conventions. You always know what you are revising, why it is on the paper, and where you are losing marks.

IB Mathematics students typically lose marks for the same handful of reasons: vague definitions, missed application or evaluation marks, weak use of subject-specific vocabulary, and rushed answers to higher-tariff questions. Our AI feedback looks at your responses the way an examiner would — command word by command word — so feedback is something you can actually act on, not a grade with no explanation.

OES does not provide official copyrighted past papers. Instead, our AI generates fresh Mathematics exam-style practice papers and revision resources that mirror the structure, difficulty and command words of real IBO (International Baccalaureate Organization) exams. That gives you unlimited practice without the legal grey area.

Who this is for

Students sitting IB Mathematics with IBO (International Baccalaureate Organization)
Anyone retaking IB Mathematics who wants targeted, focused revision
Tutors and parents supporting IB Mathematics students

Learning objectives

By the end of this topic you should be able to:

Map the full IB Mathematics specification and how the topics fit together
Apply core Mathematics concepts across number and algebra and functions and calculus
Use IB command words ("describe", "explain", "evaluate", "compare") correctly in extended responses
Plan and structure higher-tariff Mathematics questions to maximise application and evaluation marks
Self-mark your Mathematics answers against published mark-scheme conventions and identify where you lost marks
Build a revision schedule that prioritises your weakest Mathematics sub-topics in the final weeks before your exams

Common mistakes

Revising Mathematics by reading textbooks passively instead of active recall and exam-style practice
Memorising content without practising the IB command words examiners actually use
Spending time on areas you already know well, while neglecting your two or three weakest sub-topics
Writing long, unfocused extended answers that miss the specific mark points on the scheme
Leaving exam-style timed practice until the final two weeks instead of building it in from the start

Revision tips

Build a one-page Mathematics topic map covering number and algebra, functions and calculus, geometry, trigonometry and vectors, statistics, probability and modelling — tick off sub-topics as you revise them
Drill Mathematics flashcards in short, daily blocks — spaced repetition beats one long weekly session
For every Mathematics topic, attempt at least one exam-style question and self-mark against the mark scheme
Target your two weakest sub-topics each week, then let the AI Study Coach update the plan as you improve
In the final 4–6 weeks, switch to full IB-style papers under timed conditions

Key concepts

Equation vs. expression: An equation contains an equals sign and can be solved; an expression is a string of terms (e.g. 3x + 5) that can be simplified but not 'solved'.
Direct vs. inverse proportion: Direct: y = kx — as x doubles, y doubles. Inverse: y = k/x — as x doubles, y halves. Always state the constant k.
Gradient and y-intercept: For y = mx + c, m is the gradient (rise ÷ run) and c is where the line crosses the y-axis.
Pythagoras vs. trigonometry: Pythagoras (a² + b² = c²) gives you a missing side when you know two sides. Use SOH-CAH-TOA when an angle is involved.
Probability rules: P(A or B) = P(A) + P(B) for mutually exclusive events. P(A and B) = P(A) × P(B) for independent events.
Surds simplification: Break the number under the root into a product with a square factor: √72 = √36 × √2 = 6√2.

Worked examples

Question

Solve 3(2x − 1) = 4x + 7.

Solution

Expand the bracket: 6x − 3 = 4x + 7. Subtract 4x from both sides: 2x − 3 = 7. Add 3: 2x = 10. Divide by 2: x = 5. Always check: 3(2×5 − 1) = 3 × 9 = 27, and 4×5 + 7 = 27. ✓

Practice questions

Try each one before opening the model answer.

Make x the subject of y = 4x − 7.

Add 7: y + 7 = 4x. Divide by 4: x = (y + 7) ÷ 4.

Express 0.000064 in standard form.

6.4 × 10⁻⁵ (move the decimal 5 places right; negative exponent because the number is < 1).

Find the gradient of the line through (2, 5) and (6, 13).

Gradient = (13 − 5) ÷ (6 − 2) = 8 ÷ 4 = 2.

A bag has 3 red and 5 blue counters. Two are taken without replacement. P(both red)?

P(R then R) = 3/8 × 2/7 = 6/56 = 3/28.
