Guilherme G.

Experienced IB and IGCSE tutor with over 10 years of teaching in international school environments and private tutoring. I specialize in English, English Literature, Portuguese, Geography, History, Philosophy (TOK) and Humanities, combining a strong academic background (PhD, MSc, BA) with practical classroom experience at St. Paul’s School (IB & IGCSE) and Alumni School.

My teaching is centred on a communicative, student-focused approach, building confidence, critical thinking, academic writing, and exam performance. I have extensive experience preparing students for IB (Language A/B, Geography, TOK, EE) and IGCSE (Geography, ESL, Literature), as well as TOEFL, IELTS, and SAT.

I’m multilingual, inclusive, and highly experienced with diverse learners — including bilingual, expatriate, and neurodivergent students.
