The Ultimate IB Resources Hub

The International Baccalaureate (IB) Diploma Programme demands exceptional organisation, deep subject knowledge, and access to high-quality study materials. Yet many IB students waste hours searching across dozens of websites for reliable resources.

This hub brings together the best IB study materials in one place — from official formula booklets and past papers to free revision notes and AI-powered study tools. Whether you are in your first year of IB or weeks away from final exams, this guide has everything you need.

Official IB Resources Every Student Must Have

IB Subject Guides

Every IB subject has an official subject guide published by the IBO. These documents outline:

• Complete syllabus content and learning objectives
• Internal Assessment (IA) requirements and criteria
• Assessment objectives and command terms
• Suggested teaching hours per topic

Your school should provide digital or physical copies. If not, request them from your IB coordinator — they are essential for understanding exactly what you need to learn.

IB Formula Booklets

For science and mathematics subjects, the IBO provides official formula booklets that are given to students during examinations. Familiarising yourself with these booklets before the exam is crucial.

IB Physics Formula Booklet (Data Booklet)

The IB Physics data booklet contains:

• Fundamental constants (speed of light, Planck constant, gravitational constant, etc.)
• Key equations for all topics from mechanics to quantum physics
• Useful relationships for SL and HL content
• Uncertainties and SI units reference

Study tip: Do not try to memorise everything in the data booklet. Instead, practise using it during past paper work so you know exactly where to find each formula under exam pressure. Check out our detailed IB Physics formula sheet guide for a complete breakdown.

IB Mathematics Formula Booklet

The Mathematics formula booklet (available for AA and AI, both SL and HL) includes:

• Prior learning formulae
• Topic-specific formulae for algebra, functions, trigonometry, calculus, statistics, and probability
• Statistical tables

IB Chemistry Data Booklet

Contains:

• Periodic table with atomic numbers and masses
• Electrochemistry data (standard electrode potentials)
• Thermodynamic data
• Spectroscopic data (IR, NMR, mass spec reference tables)

IB Past Papers

Past papers are the single most valuable revision resource for IB students. They reveal:

• Question styles and formats the IBO uses
• How marks are allocated (crucial for exam technique)
• Which topics appear most frequently
• The depth of understanding expected at SL vs HL

Where to find IB past papers:

1. IB Questionbank (official): Your school has access through the IB’s online platform
2. Your teachers: Should have collections of past papers
3. Follet IB Store: Official source for purchasing past papers

Important note: Unlike Cambridge (CAIE), the IBO does not publish past papers freely. Sharing copyrighted IB papers online is against IBO policy. Always use legitimate sources.

IB Internal Assessment Resources

Internal Assessments (IAs) typically count for 20-25% of your final grade. Here are resources to help:

Science IAs (Physics, Chemistry, Biology)

• Nailing the IA series by Tutopiya tutors — structured approach to research questions, methodology, and analysis
• IB Science IA examples — request exemplars from your teacher (scored with criteria)
• Data analysis tools — Logger Pro, Google Sheets, or Excel for graphing and statistical analysis

Mathematics IA (Exploration)

• Choose a topic you are genuinely interested in
• Use Desmos or GeoGebra for visual demonstrations
• Aim for personal engagement — examiners want to see YOUR mathematical thinking
• Length: 6-12 pages is typical

Economics IA (Commentaries)

• Use current news articles as your stimulus
• Clearly link economic theory to real-world events
• Include relevant diagrams (hand-drawn or digital)
• Three commentaries, each 800 words maximum

English IO (Individual Oral)

• Practise your 10-minute oral presentation multiple times
• Create a clear global issue that connects your texts
• Use specific textual evidence and literary terminology
• Time yourself rigorously during practice runs

How to Use IB Resources Effectively

Create a Resource Map

At the start of each subject, create a document listing:

• Your primary textbook
• Online resources for each topic
• Past paper sources
• IA-specific materials

This prevents wasting time searching later.

Follow the Syllabus Structure

Always align your study with the official IB syllabus:

1. Check the subject guide for the topic outline
2. Study revision notes for the topic
3. Watch video explanations for difficult concepts
4. Complete practice questions
5. Attempt past paper questions on the topic
6. Review mark schemes to understand examiner expectations

Use Active Study Techniques

Passive reading is inefficient. Instead:

• Teach the concept to someone else (or explain it out loud)
• Create summary sheets from memory, then check against notes
• Do practice problems before reviewing solutions
• Use spaced repetition — revisit topics at increasing intervals
• Test yourself using AI-powered question generators like Tutopiya’s

Plan Your Revision Timeline

Timeframe	Focus
6+ months before exams	Complete syllabus coverage, start IAs
3-6 months	Topic revision, IA completion, past paper practice begins
1-3 months	Intensive past paper practice, weak topic revision
Final month	Full past papers under timed conditions, final review
Final week	Quick review of summary notes, formula booklets, rest

• PV = nRT (ideal gas equation)

Frequently Asked Questions

Where can I find free IB past papers?

The IBO restricts distribution of past papers. Your best legitimate sources are your school’s IB coordinator, the official IB questionbank (school access), and resource platforms like Tutopiya that provide IB practice questions aligned with IB standards.

Is the IB Physics data booklet the same as a formula sheet?

Yes, the IB Physics data booklet (sometimes called the formula booklet) is provided during Physics examinations. It contains fundamental constants, key equations, and useful data. You cannot bring your own formula sheet — you must use the official booklet.

How many past papers should I complete before IB exams?

Aim for at least 3-5 complete past papers per subject in the final months of revision. For your strongest subjects, 3 may suffice. For weaker subjects, do 5 or more, carefully reviewing mark schemes each time.

Are IB and IGCSE resources interchangeable?

Not directly, as the syllabuses differ. However, there is significant content overlap in subjects like Mathematics, Physics, Chemistry, and Biology. IGCSE resources can be useful for foundational topic revision, but always verify alignment with IB syllabus specifications.

What is the best all-in-one IB resource platform?

For comprehensive coverage across all IB subjects at the most affordable price, Tutopiya’s Learning Portal offers the best value at SGD 8/month for ALL subjects and levels. It combines revision notes, practice questions, AI-powered tools, and video content in one platform.
