IB Math tutor — AA & AI, SL & HL.
Renzo Diaz is an IB Math tutor based in Milan, working online with students worldwide. One-to-one tutoring across Analysis and Approaches (AA) and Applications and Interpretation (AI), at Standard and Higher Level — application-only, with every session recorded and documented.
IB Math comes in four courses, and they fail students in four different ways. AA HL breaks on proof. AA SL breaks on no-calculator pace. AI breaks on modelling judgement. So before anything else, the question is which course your child is actually taking — and where, exactly, in that course the reasoning broke.
The work starts by finding the exact step where the reasoning broke, and rebuilding from there — on a fixed weekly rhythm, against real IB exam questions, with every session recorded into a searchable archive your child keeps for their entire Diploma.
The classroom-exam gap: you understand in class, the exam says otherwise.
The IB never asks the question you practised. It asks something that looks unfamiliar and rewards only one thing: understanding deep enough to transfer. That is a trainable skill — but it is not trained by drilling one problem type.
The mid-course slide: a strong start, then a slow decline.
This is the signature of a cracked foundation, not a lack of talent. A gap from an earlier topic — functions, algebra fluency, trigonometry — quietly taxes every new chapter until the whole structure wobbles. We go back as far as needed, then forward faster.
Exam pace: they know the maths, they're just too slow.
This one is invisible until the mock exam: a student who can solve everything given unlimited time, and runs out of it in Paper 1. The fix isn't more content — it's method selection. Most problems admit several correct routes; the skill is recognising which one the question is quietly asking for, and taking it. That's trained deliberately, with timed work, every week.
The IA workload: it became a second full-time job.
The Exploration rewards a clear question, appropriate mathematics, and honest reflection — not complexity. I guide topic selection, structure, and draft feedback, strictly within IB academic honesty rules. The work stays your child's; the direction stops being guesswork.
AA vs. AI: choosing between them, or doubting the choice already made.
The decision matters less than people fear, and more than schools explain. AA rewards algebraic fluency and proof-style thinking; AI rewards modelling, interpretation, and intelligent calculator use. I help you decide from the university courses you're actually aiming at.
Coverage
Four courses. Find the one your child is actually sitting.
AA and AI are different subjects wearing the same name, and SL and HL are different workloads again. Each has its own page, with the situations, the syllabus coverage and the exam technique specific to it.
The method
A documented weekly system, not ad-hoc lessons.
Every week opens with what went wrong last week — because wrong answers are the real diagnostic information. We work on what's live from school, advance the syllabus in order, and record everything into an archive you and your child can search any time. You always know exactly where things stand.
Documented, not promised
Grade 3 → Grade 7 in IB Math AI SL.
Aline arrived at the start of her Diploma with a Grade 3 and finished with a Grade 7 — a 7 in each written paper. Her review is on the results page, linked to its original on Google.
