Meet the Founder & Lead Tutor

Suneel Gupta

Suneel Gupta

B.E. (India) · MSc Physics (UAB Barcelona) · 30+ Years Teaching Experience

Suneel holds a Bachelor's degree in Engineering from India and a Master's degree in Physics from the Universitat Autonoma de Barcelona (UAB). He has spent over 30 years teaching mathematics and physics across international curricula.

He founded 4S Academy on a simple principle: every student can excel with the right guidance.Based in Barcelona, he works with families from the city's leading international and trilingual schools — including BFIS (Benjamin Franklin International School), the American School of Barcelona (ASB), Europa International School, The British School of Barcelona, St Peter's School, Hamelin-Laïe International School, Agora Sant Cugat International School, Kensington School, the Lycée français de Barcelone and other French‑medium programmes, Deutsche Schule Barcelona, Oak House School, and others — plus students online worldwide.

His teaching is concept-first and practice-heavy. Students do not just memorise formulas. They learn to think through problems they have never seen before. That is what separates exam success from real understanding.

Families seeking advanced maths depth often value his India-rooted rigour in problem-solving, combined with an international, student-friendly teaching style that works across boards and age groups.

Teaching That Actually Works

We don't just cover content. We rebuild how students reason — in Maths and Physics, on standardised tests, and when using AI tools with judgement — so school demands and exams feel manageable.

Concept-First, Exam-Ready

We teach the 'why' before the 'how'. Students who understand deeply never freeze in an exam.

Curriculum-Specific Knowledge

Deep expertise across IB, IGCSE, A-Level, MYP, Digital SAT, ACT, and AP — plus structured AI literacy. Targeted preparation, not generic drill.

Structured Progress Tracking

Every session follows a plan. Every milestone is tracked. Students and parents always know where they stand.

Targeted Practice Materials

Worksheets and question sets focused on each student's gaps — layered with adaptive practice when it helps — not recycled papers alone.
