AQA A Level Physics Paper 3 Astrophysics 7408/3ba 2025 Qp

Get the official AQA A-Level Physics Paper 3 Section B Astrophysics question paper from the June 2025 series (7408/3BA) — the exact option-specific booklet sat on the morning of 17 June 2025 by candidates who chose Astrophysics as their Paper 3 optional topic. This free downloadable PDF contains every Astrophysics question contributing to the 35 Section B marks, in the original AQA layout candidates faced in the real exam — perfect for timed, exam-condition mocks targeted purely at the option content.

Section B Astrophysics covers the full optional specification: optical telescopes (refracting, reflecting, Cassegrain), non-optical astronomy across radio, infrared, ultraviolet and X-ray, classification of stars by luminosity and the Hertzsprung-Russell diagram, absolute and apparent magnitude, stellar spectral classes, supernovae, neutron stars and black holes, cosmology (Doppler effect for light, Hubble's law, Big Bang theory, quasars), and the detection of exoplanets. Pair it with the matching Section A practical-skills paper and the official 7408/3BA mark scheme on markscheme.net to lock in the exam 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 Section B option and want authentic, exam-condition practice on the Astrophysics topic only — without the practical-skills section diluting their option-specific revision time. It is equally valuable for Year 13 candidates entering the final stretch of revision, Year 12 students stretching ahead, retake students aiming for an A or A*, and home-schooled learners working independently.

Physics teachers, private tutors, and astrophysics-option leads can use this official AQA option booklet to set timed Astrophysics-only mocks (around 50 minutes for 35 marks), run topic walkthroughs on cosmology and stellar evolution, benchmark student progress against the most recent series, and pinpoint weaknesses in telescope theory, magnitude calculations, or Hubble's law applications. Parents supporting revision at home can print this paper, time their child to the official limit, and combine it with the markscheme.net mark scheme for examiner-aligned feedback.
