Why BAAO coaching is hard to find
The BAAO sits above the syllabus, so most tutors cannot teach it
A tutor who has only taught Astrophysics to A-Level has not met these problems. Competition papers are not harder versions of the syllabus, they are a different kind of work, and coaching them means having sat them. That is why most agencies quietly decline this, and why students who want to prepare seriously are usually left with a past-paper archive and no one to mark it.
We do teach it. Every Oxbridge Mentors tutor is a graduate of the University of Oxford or the University of Cambridge, and the ones who coach the BAAO sat it themselves and scored at the top of it. That is the whole reason we can offer this when others do not.
Who it is for
Applicants aiming at the most selective courses, where strong grades are the baseline rather than the differentiator.

What is the BAAO?
The British Astronomy and Astrophysics Olympiad (BAAO) is the senior UK competition in astronomy and astrophysics, run by the British Physics Olympiad. It applies A-Level physics and mathematics to problems about stars, orbits, and cosmology, and its top performers are selected for the UK teams at the international astronomy and astrophysics olympiads.
The BAAO is the astronomy and astrophysics strand of the British Physics Olympiad. Its problems take familiar physics, gravitation, orbits, radiation, and geometry, and apply it to astronomical settings: the motion of planets and binary stars, the physics of stellar interiors, distances across the universe.
It is sat by strong Year 13 physicists, usually those who have already met the physics olympiads, and the top scorers are selected towards the UK team at the International Olympiad on Astronomy and Astrophysics (IOAA). Astronomy challenges for younger year groups sit below it as stepping stones.
For a physics applicant, the BAAO is a distinctive signal: it shows both problem-solving ability and a genuine, self-directed interest in astrophysics that reads well in a personal statement and at interview.

Who Should Enter
Year 13 physicists with a real interest in astronomy who are already comfortable with olympiad-style problem-solving. It suits future physics and astrophysics students and complements, rather than replaces, the main physics olympiad.
- Aimed at senior students, typically Year 13.
- Entered through your school.
- Solid A-Level physics and mathematics, plus some prior olympiad experience, make it far more approachable.

How Our Tutors Help With the BAAO
1
Coaching from physics graduates who can teach the astrophysics toolkit: orbital mechanics, magnitudes and distances, blackbody radiation, and stellar physics.
2
Practice on past BAAO papers with feedback on setting up astronomical problems and keeping units and orders of magnitude under control.
3
A plan that sequences BAAO preparation after the core physics olympiad so the student builds up rather than takes on everything at once.
4
Support turning a genuine interest in astronomy into strong personal-statement and interview material.
Tutoring is one-to-one and online, matched to the competition and the student. Packages start from over £50 per session with graduate mentors.

How to Prepare
- Get comfortable with orders of magnitude and units: astrophysics problems live or die on careful bookkeeping of very large and very small quantities.
- Revise gravitation and circular motion thoroughly, since orbits are at the heart of many questions.
- Read a little real astrophysics beyond the syllabus so the contexts in the paper feel familiar rather than alien.

BAAO: Frequently Asked Questions
No. The BAAO is built on A-Level physics and maths applied to astronomical contexts, so a strong physicist can succeed without a separate astronomy course, though some background reading helps.
Usually yes. The BAAO assumes olympiad-level problem-solving, so most students meet the British Physics Olympiad before or alongside it.
Yes. It signals problem-solving skill and self-driven interest, both of which strengthen any physics-related application.
