Renzo Diaz — IB Math (AA/AI) and Physics (SL/HL) tutor, online in CET. Teaching IB one-to-one since April 2016. M.Sc., Politecnico di Milano.
Ten years teaching IB Math and Physics one-to-one, every lesson myself, and I publish the results I can prove:
• a final 7 in IB Physics SL (May 2025, from a 3, the first exam session of the new syllabus)
• a final 6 in IB Math AI HL (May 2025, from a 4)
• Grade 7 in both IB Math AI SL exam papers (May 2024, from a 3)
How I teach: bring the question your child keeps getting wrong. I find the first step that isn't reliable — a missing concept, a misread graph, an algebra slip — rebuild the explanation around how your child thinks, then change the question to check the fix holds. Each week starts from what is live at school and last week's wrong answers.
IB Mathematics: Analysis and Approaches (AA) — algebra, functions, calculus and proof, Paper 1 without a calculator and, at HL, Paper 3. Applications and Interpretation (AI) — modelling, statistics and the graphic display calculator. AA or AI, SL or HL: I help families decide from the university courses the student is aiming at.
IB Physics, SL and HL, on the current guide: the five themes, Papers 1A, 1B and 2, data-based questions, uncertainties and graphs; at HL, the extensions and the long extended-response questions. My engineering training (M.Sc., Politecnico di Milano) shows in how I teach it: define the system, state the assumptions, then connect the model to the mathematics.
The IA and the Extended Essay: guidance only, within the IB's academic-integrity rules — the student writes every word.
