Meet the Founder & Lead Tutor
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.
Summer Camps and Intensives
Concentrated July and August blocks for mathematics (all grades) and physics (Grades 9–12) across IB, A-Level, and Spanish national programmes, plus Digital SAT, AP Calculus, and AP Physics. Suitable for autumn readiness and November-oriented IB preparation. In person in Barcelona or online worldwide; exact strands after enquiry.
July and August Windows
Camp-style blocks and shorter intensive weeks; strand matched to your goals, including November-oriented IB preparation.
Papers and Strategy
Where exams are the goal, syllabus work is combined with timed papers and debrief — same approach as term-time tutoring.
