Why September matters
The year is shaped
in the first term
Students who start strong in September rarely spend the spring catching up. A full academic year of weekly sessions builds understanding steadily, so by the time exams arrive, revision is reinforcement — not first contact with the material.
01
Start strong, stay ahead
Weekly sessions from September mean no scramble to catch up before mocks or finals — steady progress across the whole year, not a last-minute push.
02
One expert, start to finish
No rotating tutors, no handovers. Every session is led personally by Dr Stefanidis, all year, with the same standard that’s placed students at Oxford and Cambridge.
03
Built for how you learn
Live online, small groups or 1:1, with interactive materials and self-marking practice — flexible scheduling across time zones, including the UK and the Gulf.
The 2026/27 courses
Choose your subject.
Start in September.
GCSE, A-Level and IB — for students in the UK, the Gulf and worldwide. Weekly slots are capped to protect the quality of small-group teaching, so September availability is genuinely limited.
September enrolment open
Physics
GCSE · A-Level · IB · International
Mechanics, fields, particles and beyond — from a working ATLAS physicist who teaches it as a story, not a syllabus, week after week all year.
Filling for September
Mathematics
GCSE · A-Level
Pure, mechanics and statistics taught for genuine fluency — the foundation that holds up under exam pressure in June.
September enrolment open
Further Maths
GCSE · A-Level · IB · International
Extension pure, mechanics and statistics for students pushing beyond the core specification — the edge that matters for competitive STEM admissions.
Few September slots left
Chemistry
GCSE · A-Level
Organic, physical and inorganic chemistry made coherent — clear models that make the hard topics click, term after term.
September enrolment open
Computing
GCSE · A-Level · IB · International
Programming, algorithms and computational thinking, taught with the same rigour as the sciences — from first principles through to full coursework.
September enrolment open
Biology
GCSE only
Core and additional biology across the full GCSE specification, taught with the same clarity and structure as every other subject.
