RENZO DIAZ — Reference library
The Renzo Diaz Index
A reference library for IB families: how the Diploma works, how Mathematics and Physics are assessed, which course to choose and what universities ask for. Every piece lists its sources and says what each figure counts.
Search for advice on the IB and you mostly find recycled definitions and directories padded for keywords. This library is the opposite: specific, long-form answers to the questions families ask before they decide, written by someone who has taught IB Mathematics and Physics since 2016.
It grows slowly, on purpose. Today it covers the IB Diploma Programme in Mathematics and Physics, and IGCSE joins when it has a first real piece of its own. Nothing is written to hit a word count.

Five pieces, one for each section, that answer what families ask first.

Every piece in the library
How each piece is checked
Every piece lists its sources, says what each figure counts and links the official page it relies on. Exam structure, weights and requirements are read from the IB’s own guides and from each university’s admissions pages rather than repeated secondhand.
