The Renzo Diaz Index
A reference library, not a blog — where the method behind the coaching gets written down: how IB and IGCSE actually work, how to read a predicted grade, how to tell a real result from a marketing claim.
Search for advice on the IB and IGCSE and you mostly find recycled definitions and directories padded for keywords. This is the opposite: specific, long-form answers to the exact questions families ask before they apply — written by someone who has spent a decade inside the syllabus, not by someone optimising for a phrase.
It grows slowly, on purpose. Every piece here holds itself to the same standard as the results page: verifiable, dated, specific — nothing written just to hit a word count.
For Students
Study method and revision strategy, and the specific mechanics of IB and IGCSE assessment that no syllabus document explains.
Programs
IB, IGCSE, and the Italian system, organised by what a student is actually enrolled in — Mathematics AA and AI at SL and HL, Physics, IGCSE Core and Extended — with exam structure and marking folded into each program rather than a separate page that fits none of them well.
Schools
Milan's international schools, and the curriculum decisions each one makes long before a family ever needs a tutor.
University
How IB and IGCSE subject choices carry through to university admissions — requirements, grade thresholds, and what actually matters where.
Resources
Frameworks, checklists, and reference tools, built to be used once and kept — not scrolled past.
