Why a high R² does not prove a model, and how to choose, test and defend a function you can actually justify.
What each section is actually for, the mistake I see in each one, and an order that lets the mathematics show.
Why length is a symptom, what going over costs you in communication, and nine ways to cut a draft without losing marks.
Six places to reflect as you work, why generic limitations earn little, and a quick highlighter check before you submit.
Why claiming passion earns nothing, and twelve places where your own decisions can show on the page.
How to choose what to measure, sample sensibly, deal with messy values and name limitations so your data holds up.

These pages are free and stay free, but they are general and your IA is not. Send me your research question, or whatever exists so far, and I will tell you in writing whether the topic has a ceiling on it, where the marks are going, and what to change first. That costs nothing and it comes back within 24 hours.
Written by a serving IB Diploma and Career-related Programme Coordinator and Head of Mathematics, who reads internal assessments across every subject group every year. If you then want the whole draft reviewed properly against all five criteria, that is the paid one, and it is refunded if it does not name at least three specific things to fix.
