EDP-004 · Individual Diagnostic Tutoring
Your child studies at an international school. Who ensures mastery?
The school advances. The curriculum is demanding. But between “keeping up with the class” and “mastering the content” there’s a gap that shows up at assessment time. We find it before it costs the grade.

Subjects We Cover
Engineering-grade diagnostic tutoring for the core international curriculum subjects. Each discipline receives its own FMEA gap analysis.
Mathematics
Algebra, functions, calculus, statistics, geometry. We separate conceptual gaps from procedural errors.
Physics
Mechanics, waves, electricity, thermal physics. We identify whether the gap is math-based or conceptual.
Chemistry
Stoichiometry, bonding, energetics, organic chemistry. Precision in calculations and conceptual chains.
Economics
Micro & macroeconomics, quantitative methods, diagram analysis. We fix the reasoning behind the graphs.
Biology
Cell biology, genetics, ecology, human physiology. Structured analysis of interconnected systems.
Additional Subjects
Portuguese, English Language, and other disciplines with logical structure. Assessed case by case in the diagnostic session.
The International Curriculum Problem
IB and IGCSE don’t forgive gaps. They are spiral curricula — every new topic depends on everything that came before.
Language barrier masked as content gap
The student understands in Portuguese but freezes when required to reason, read, and answer in English. The gap isn’t math — it’s interface.
Missing prerequisite
Year 10 demands full algebraic mastery from Year 8. The school moved on. The student didn’t. Nobody went back to fix it.
Grade vs. mastery
A 5 in IB looks “fine.” But at competitive universities, the difference between 5 and 7 is the difference between rejection and admission.
FMEA Diagnostic: How It Works
Failure Mode & Effects Analysis — the engineering method used by NASA, Boeing, and Toyota to find failures before they cause problems.
Bilingual mapping
We analyse errors in the curriculum language (English) and identify whether the failure is conceptual, linguistic, or procedural.
Impact-based prioritisation
Each gap is scored by severity × frequency × detectability. We fix what impacts the grade most.
Syllabus alignment
The correction plan aligns with the student’s specific syllabus. We work with command terms, assessment criteria, and exam formats.
What Sets Us Apart
This isn’t another tutor repeating the lesson more slowly.
Year 7 to university — one vision
We teach today’s content knowing what will be required at Diploma, SAT, and application level.
Technical report per session
Every session generates documentation: what was covered, error patterns identified, progress measured.
Sessions in Portuguese or English
We explain in Portuguese when it accelerates understanding, practise in English when the exam requires it.
Engineering diagnosis, not intuition
FMEA classifies each error by type, severity, and impact. Data, not guesswork.
IB command terms & criteria
We work with justify, evaluate, analyse — the rubrics and assessment format the IB actually tests.

If the plan includes American universities, IB diagnostic connects directly to our SAT Pathway.

Individual sessions have no class overhead. When we know exactly where the student stands, every minute counts.
What Families Say
Real feedback from parents and students we work with.
“My son passed the admission tests for high school thanks to his professionalism and help with the subjects. He is well adapted and happy at his new American school.”
— Edmar · Google Review
“Your classes helped me a lot. I like the Zoom classes and you are a perfect teacher, always helps us to learn in a simple way. I learned a lot and improved myself to be more organized.”
— Amyr · IB Student
“I had classes with Prof. Robert since middle school. His dedication and method made all the difference in my academic journey. Now, admitted to University College London (UCL).”

+🇧🇷 Resumo em Português
O EDP-004 é um programa de tutoria individual com diagnóstico de engenharia para alunos de escolas internacionais (IB, IGCSE, A-Level, AP). Usamos o método FMEA para mapear lacunas invisíveis por disciplina, priorizar o que mais impacta a nota, e corrigir na raiz.
Sessões individuais, presenciais no Leblon ou 100% online. Português e inglês. Relatório técnico por sessão. Atendemos alunos no Brasil e no exterior (Suíça, Europa, EUA, LatAm).
Disciplinas: Matemática (AA/AI), Física, Química, Economia, Biologia, e outras sob consulta.
Investimento e formato são definidos caso a caso, após a conversa inicial gratuita de 15 minutos — onde entendemos a situação do aluno e explicamos como o método funciona na prática.
The school advances. Your child needs to master, not just keep up.
Schedule a free 15-minute conversation. We will discuss your child’s situation and explain how the method works.
