Your IA usually starts the same way: a blank document, a bold title, and the quiet belief that you’ll find the “perfect” idea by tonight.
Then the idea list grows. So does the stress.
Because an IA isn’t just a topic. It’s weeks of decision-making: what to model, what to measure, what to explain, what to cut. The right IB Math IA topic doesn’t feel like a genius move. It feels like a topic you can carry calmly from first draft to final reflection.
Start with curiosity, then force it to become a question
A strong IA usually begins with something personal: a sport, a routine, a game, a commute, an obsession with charts. But personal doesn’t mean vague.
Your job is to turn “I like this” into “I can investigate this.” A good sign is when you can write the research question in one sentence and immediately name the techniques you’ll use (regression, calculus, probability, sequences, geometry).
Most IA ideas fail for one reason: they try to be a documentary.
A topic like “model the entire stock market” sounds impressive, but it becomes shallow fast. Examiners reward clarity and mathematical depth, not an oversized storyline.
A beautiful topic with weak data becomes a messy IA.
Before you commit, prove one of these is true:
you can access a dataset with enough rows to model meaningfully
you can collect data reliably within a week
you can simulate data with clearly justified assumptions
If your topic relies on data you “might” find later, pause. Your future self will not thank you.
Comic about finding tiny datasets
Use feedback early, not only at the end
The best time to get feedback on your IA topic is when changing direction is still cheap.
Bring your teacher two or three options, each with:
a one-sentence research question
the planned math techniques
where the data will come from
Then refine quickly.
RevisionDojo can speed this up using a full workflow: Study Notes to confirm concepts, the Questionbank to practice the methods you’ll use, AI Chat to unblock steps, and Tutors if you need a second set of expert eyes.
A strong IA topic is rarely the flashiest idea in the room. It’s the one with stable data, clear math, and a scope small enough that you can explain every step without rushing.
If you want to choose your IA topic with less guesswork, use RevisionDojo as your loop: explore ideas in guides, confirm techniques with Study Notes, practice methods in the Questionbank, and pressure-test your confidence with Mock Exams and Predicted Papers (for exam prep) while your IA develops.
