Beyond the standard
school curriculum
Competitive entrance examinations and Olympiads demand far more than syllabus knowledge. Students must think flexibly, reason independently and solve unfamiliar problems under pressure.
My online STEM entrance exam preparation is designed for academically ambitious students aiming for highly selective university pathways in Physics, Mathematics, Engineering, Computer Science and related STEM disciplines.
The emphasis is always on developing genuine problem-solving ability, mathematical maturity and intellectual confidence — not simply memorising techniques.
Specialist preparation for
competitive university admission
From diagnostic assessment
to confident performance
Developing thinkers,
not memorisers
Competitive examinations are designed to identify students who can think independently. Success comes from flexibility, persistence and intellectual curiosity.
Lessons therefore focus on reasoning processes rather than shortcuts. Students are encouraged to explore, test ideas, make mistakes and develop resilience in problem-solving.
This creates not only stronger exam performance, but also deeper mathematical and scientific maturity that benefits future university study.
Universities My Students
Have Progressed To
Over the past 30 years, I have helped students prepare for some of the world’s most competitive university courses, and continued supporting many of them once they arrived. My students have progressed to leading universities in the UK and internationally, including:
United Kingdom
-
University of Oxford
-
University of Cambridge
-
Imperial College London
-
UCL
-
King’s College London
-
University of Manchester
International
-
ETH Zurich
-
Caltech
-
New York University
-
Boston University
-
Sorbonne University
University destinations reflect the progression of individual former students. Phi Tuition is independent and is not affiliated with, sponsored by or endorsed by any of the universities listed.
Planning entrance-exam preparation
Preparation is most effective when it starts with a clear target, an honest assessment of current skills and a realistic timetable.
Which admissions tests do you support?
Preparation is available for ESAT, TMUA and STEP, alongside Physics and Mathematics Olympiads and technical STEM interviews.
When should preparation begin?
Ideally several months before the test, allowing time to strengthen foundations before moving to timed papers and advanced questions.
Is this suitable for international students?
Yes. Lessons are fully online and can be adapted to students following A-Level, IB or comparable international programmes.
Do lessons only use past papers?
No. Past papers are important, but preparation also develops the underlying reasoning, subject knowledge and problem-solving habits needed for unfamiliar questions.
Elite preparation for
students aiming higher
Specialist online preparation for ambitious students applying to Oxbridge, Imperial and other competitive STEM courses, or pursuing advanced mathematical and scientific challenges.
