IA Modelling Planner

Walk from empty page to a submitted IA in six steps. Start with the scoping plan (11 pre-writing prompts checked against our own planning bands A-E, 0-3 each), then draft each criterion with a “Get AI feedback” button that grades your paragraph against the official IB Math Modelling IA descriptors. When your draft is ready, one click hands the whole thing off to the full AI IA Review. 📖 Step-by-step guide →

New: the IA planner has section-by-section frameworks for every IA type and a milestone planner. Feedback here comments on your paragraph; it never writes it for you.

⚠ Your IA must be your own work — this can cost you your Diploma. This planner is a study aid, not a co-author: it coaches with questions and comments, and never writes any part of your exploration for you. Submitting AI-written, copied or paraphrased text as your own is academic misconduct under the IB's Academic Integrity Policy — the consequences can range from losing marks and a 0 for the IA, to, in serious or repeated cases, not being awarded the Diploma at all. That's a deliberate design choice, not a limitation: a study aid that only asks questions is safe to acknowledge and cite, where a generic AI chatbot that writes for you is not. If you use this tool, acknowledge it as your school's policy requires. See how to use help and AI honestly and full terms.

Ten minutes of scoping saves ten hours of rewriting later. This mirrors the pre-writing plan Pete uses with real IB students — every prompt maps to a planning band (A-E, 0-3 each).

Have data already? Paste it into Model my data for every step of each model with your numbers, and copy it back into Desmos. IA modelling, step by step.

1 Pick a real-world topic

Good IAs start with genuine curiosity. Aim for something you'd actually want to know — coaches, teams, hobbies, ecology, local businesses.

The IB rewards personal engagement (Criterion C). Generic textbook topics rarely score above 3/4.

2 Source your data

You need at least 10 clean data points, ideally 20+. Bookmark the source now so you can cite it in Criterion B.

Primary data (you collect it) scores higher on Criterion C than secondary (someone else's).

JPEG, PNG, WebP or HEIC · max 8 MB · auto-deleted after 30 days. When you get AI feedback below, the AI can see this alongside your write-up — it never becomes part of your IA text.

AI marking is for our own questions and your own work only — please don’t upload official IB exam papers or mark schemes.

3 Pick a model

Which mathematical model best fits the relationship you're testing?

4 Draft Criterion A · Presentation

Rewrite your topic + data + model choice as a coherent introduction. Aim for 250-400 words.

5 Draft Criterion C · Personal engagement + Criterion D · Reflection

Show why THIS problem matters to you and what surprised you. These are the two criteria most IB students under-cook.

6 Draft Criterion E · Use of mathematics

Show the actual maths — fitted parameters, residual analysis, error bars, validity checks. This is where the top-band marks live.

A Presentation (4 marks) — coherent, concise, well-structured.
B Mathematical communication (4) — accurate notation, terminology, forms.
C Personal engagement (3) — genuine curiosity, independent thinking.
D Reflection (3) — critical, meaningful reflection on findings + limitations.
E Use of mathematics (6) — sophisticated + correct math beyond SL syllabus level.

Total: 20 marks · Weight: 20% of your final grade.

The full review reads your assembled draft and grades all five official IB criteria (A–E, 20 marks). Pro includes 4 full reviews a year; otherwise it is €5 a review (the IA package includes 5). The paragraph feedback on this page is free.

Reminder: your submitted IA must remain your own work — see the academic-honesty notice near the top of this page.
