AQA A Level Physics 7408/3a Astrophysics 2025 Question Paper

Get the official AQA A-Level Physics Paper 3 Astrophysics question paper from the June 2025 series (7408/3A) — the exact exam sat on the morning of 17 June 2025. This free downloadable PDF gives you both compulsory Section A (practical skills and data analysis) and Section B (the Astrophysics optional topic), in the original AQA layout candidates faced in the real exam. Perfect for timed, exam-condition mocks.

Section B covers the full Astrophysics specification: optical telescopes (refracting, reflecting, Cassegrain), non-optical astronomy, classification of stars by luminosity and the Hertzsprung-Russell diagram, absolute and apparent magnitude, stellar spectral classes, supernovae and black holes, cosmology (Doppler effect, Hubble's law, Big Bang theory, quasars), and the detection of exoplanets. Pair this paper with the matching AQA 7408/3A June 2025 mark scheme on markscheme.net to self-mark accurately and lock in the technique that secures top grades in the 2026 series.

This question paper is built for AQA A-Level Physics (7408) students who chose Astrophysics as their Paper 3 optional topic and are preparing for the 2026 exam series. It is equally valuable for Year 13 students approaching the final stretch of revision, Year 12 students stretching ahead, retake candidates aiming for an A or A*, and home-schooled students working independently with no in-class teacher support.

Physics teachers, private tutors, and astrophysics-option leads can use this official AQA paper to set timed mocks, run practical-skills walkthroughs, benchmark student progress against the most recent series, and identify weak areas in cosmology, stellar classification, or telescope theory. Parents supporting revision at home can print this paper, time their child to the official 2-hour limit, and combine it with the markscheme.net mark scheme for honest, examiner-aligned feedback — even without a physics background.
