Why students choose FourtyFive
## Six reasons it beats a textbook every time.
A question bank is only useful if the questions are good, the marking is honest, and the next question is the right one. FourtyFive earns its place on all three.
Personalised IB revision
The algorithm watches every answer and re-orders your next questions so you spend time on the topics that actually move your grade — not the ones you already know.
Past-paper-style questions
Every question is original, written in-house to match the style, difficulty and command terms of Papers 1, 2 and 3 — and tagged to the current syllabus.
Answer your way
Handwrite with an Apple Pencil, type, or use a USB writing tablet on any laptop. The AI Examiner marks handwriting to the same IB mark scheme as typed answers.
AI Examiner feedback
Every response is marked mark by mark by an AI trained on IB command terms. You get marks, method credit and a sentence on what to fix — in seconds.
Mapped to the syllabus
Every question is tagged to a specific IB syllabus statement, paper and command term. You're not revising a textbook chapter — you're revising the assessment objective.
Study Profile & analytics
A topic-by-topic mastery score per subject, updated after every answer. You see what's strong, what's slipping and what to revise next — without parents asking.
How it works
## Three steps from "I'm stuck" to "got it."
01
Rate your topics
Tell us how you feel about every topic in your subject — from "haven't covered it" to "got it." Takes about 6 minutes per subject and builds your starting Study Profile.
02
Practise, your way
Pick a topic, a paper, a difficulty — or let the algorithm pick. Hand-write or type. The IB question bank serves the next question that actually moves your mastery.
03
Get examiner feedback
The AI Examiner returns a mark, method credit and what to fix, drawn from our mark scheme for that question. Your weak topics rise to the top of the next session.
How we compare
## FourtyFive vs. the way you revise now.
A textbook teaches. A past-paper PDF tests. A chatbot guesses. An IB question bank with examiner-aligned AI marking does all three — and remembers what you got wrong.

The basics
## What is an IB question bank — and why does it matter?
An **IB question bank** is a searchable library of practice questions written in the style of the International Baccalaureate Diploma Programme exams. The best ones are organised by subject, topic and paper, mapped to the current syllabus, and updated when the IBO publishes a revised guide. A bad one is a PDF dump of recycled questions with no answers.
FourtyFive sits firmly in the first camp. Our IB question bank covers six IB Diploma subjects today — [Math AA](https://fourtyfive.org/ib-question-bank/math-aa), [Math AI](https://fourtyfive.org/ib-question-bank/math-ai), [Physics](https://fourtyfive.org/ib-question-bank/physics), [Chemistry](https://fourtyfive.org/ib-question-bank/chemistry), [Biology](https://fourtyfive.org/ib-question-bank/biology) and [Economics](https://fourtyfive.org/ib-question-bank/economics) at both SL and HL — and every question is tagged to a syllabus point, paper (1, 2 or 3), command term and difficulty band. Start a session and you can drill into a single sub-topic, or let the [personalisation algorithm](https://fourtyfive.org/algorithm) pick a mix that targets your weakest areas.
### What makes a good IB question bank?
- **Syllabus-mapped, not subject-mapped.** Every question points at a specific syllabus statement so you can revise the actual learning objective being tested.
- **Examiner-aligned marking.** A mark is only useful if you understand why you earned it. Good question banks return method credit, not just totals.
- **Answer-anything input.** The real IB exam lets you handwrite — your practice should too. Typing-only banks teach a different muscle.
- **Adaptive ordering.** Going through questions in chapter order is the wrong way to revise. The next question should be chosen for you, based on your last few answers.
### How FourtyFive compares to other IB resources
Textbooks are dense, but end-of-chapter exercises rarely match exam style. PDF compilations of past papers exist, but the IBO owns the copyright and sites that redistribute them sit in a legally grey area — and they don't mark your answers. Generic AI tutors will happily help, but they don't know the IB mark scheme and will invent marks that don't exist.
FourtyFive combines a syllabus-mapped IB question bank, [AI Examiner marking](https://fourtyfive.org/for-students) aligned to IB-style mark schemes, and a personalisation engine that learns from every answer you give. That's why students use it for the day-to-day practice work in the run-up to mocks and the May or November IB session.
### Are FourtyFive questions real past papers?
No — the IBO owns the copyright on real past papers and we don't redistribute them. Every question on FourtyFive is original, written in-house to match the style, difficulty and command-term language of Papers 1, 2 and 3. That also means we can generate fresh similar questions on demand for Pro users, which a fixed past-paper bank can't.
FAQ

What is an IB question bank?
An IB question bank is a searchable library of practice questions modelled on the International Baccalaureate Diploma exams — organised by subject, topic, paper and command term, mapped to the live syllabus. FourtyFive's IB question bank covers six IB Diploma subjects at SL and HL with syllabus-mapped questions, IB mark-scheme marking and personalised next-question recommendations.
Which IB subjects does FourtyFive's question bank cover?
Six IB Diploma subjects at both SL and HL: Mathematics: Analysis and Approaches (Math AA), Mathematics: Applications and Interpretation (Math AI), Physics, Chemistry, Biology and Economics. More subjects are on the way — you can see the shortlist in the "coming soon" strip on this page.
Are the questions real IB past papers?
No — the IBO owns the copyright on real past papers and we don't redistribute them. Every question on FourtyFive is original, written in-house to match the style, difficulty and command terms of the IB exam, and tagged to the current syllabus. This also lets us generate fresh similar questions on demand, which a fixed past-paper bank can't.
Does the AI mark Paper 1, Paper 2 and Paper 3 questions?
Yes. The AI Examiner marks questions across every paper in each subject we cover, including the long-response and data-response styles. For Math AA and Math AI that's Papers 1, 2 and 3 at HL and Papers 1 and 2 at SL; for Physics, Chemistry, Biology and Economics it's the corresponding papers in each subject's IB specification.
How is FourtyFive different from Revision Village, RevisionDojo or Save My Exams?
Most IB question banks give you questions and a solution. FourtyFive closes the loop by marking your answer mark by mark against our scheme for that question, building a topic-by-topic mastery profile from every attempt, and recommending the next best thing to revise. It also natively supports handwritten Apple Pencil answers — most competitors only accept typed input.
Can I use an iPad and Apple Pencil with the question bank?
Yes. FourtyFive is iPad-first and natively supports Apple Pencil handwriting for Math, Physics, Chemistry, Biology and Economics working. The AI Examiner marks handwritten answers to the same IB mark scheme standard as typed answers. If you don't have an iPad, a USB writing tablet plugs into any Mac, Windows or Chromebook laptop and gives you the same workflow.
Is FourtyFive's IB question bank free?
Yes — the Free plan covers personalised IB revision and 50 AI-marked checks per month from the question bank, with no card needed. Academic Weapon (the Pro plan) raises that to 200 checks per month and unlocks AI Tutor Chat plus on-demand generation of similar questions with mark schemes. Billing runs through Paddle at one monthly price.
Is FourtyFive endorsed by the IBO?
No. FourtyFive is an independent IB revision platform. IB® is a registered trademark of the International Baccalaureate Organization, and we are not affiliated with the IBO. We do not redistribute IBO copyrighted materials.
