Source paper: Mathematics Part A FOI release, member FOI-20210708-1 - Data/4308.pdf. The intact cover identifies Algebra and Analysis II for Mathematics and Philosophy, AC2(P), formal code 4308, Tuesday 18 June 2013, 9.30am to 11.30am. The five-page source has six questions, in Algebra and Analysis sections, with no printed part marks.

Source: Mathematics Part A release, member FOI-20210708-1 - Data/4307.pdf, dated 17 June 2013. All 22 source leaf parts are answered below.

The department's solution-release policy excludes ordinary odd years; bounded exact-paper checks found no matching advertisement of full or selected worked answers. No parts are skipped.

The six question bodies coincide exactly with questions 1–6 of paper 4301; their solutions are reused verbatim while retaining this paper's distinct cover identity and section tree.

Source: Oxford mathematics examination release, private bundle Part A 2007 11-1.pdf, pages 5–9. The printed cover identifies both mathematics and mathematics and statistics. The complete editable transcription is retained in the private examination archive.

This printed variant of AC2 was released in FOI 20210708 1 Data. Its localized difference is the finite-dimensional wording in 2(i), while the later dimension formula still uses $n$. The solutions are reused from the corresponding native-paper draft, with $n=\dim V$ made explicit in that part. The full statement transcription is held separately.

Source: Mathematics release, bundle Part A 2007 11-1.pdf, pages 65–70. The six-page paper is shared by Mathematics and Mathematics & Statistics Part A, dated 17 June 2008. Its three printed sections are Algebra, Analysis and Differential equations.

Bounded exact-paper checks found no matching advertisement of worked answers. All nine questions, their printed parts, and their unnumbered tasks are answered. Full source statements remain in the private archive transcription.

Source: Mathematics release, supplied bundle Part A 2007 11-1.pdf, pages 125–131. The seven-page paper is dated 23 June 2009 and serves Mathematics and Mathematics & Statistics Part A. Full source statements are retained in the private editable transcription.

Bounded exact-paper checks found no matching advertisement of worked answers. Every printed task and surrounding unnumbered request is covered, with explicit qualifications for the two source formula conventions noted below.

Source: Mathematics release, supplied bundle Part A 2007 11-1.pdf, pages 195–202. The paper is dated 22 June 2010 and serves Mathematics and Mathematics & Statistics Part A.

Bounded exact-paper checks found no matching answer advertisement. All printed parts and their surrounding unnumbered requests are answered. The literal source is retained in the private editable transcription.

Source: Mathematics release, supplied bundle Part A 2007 11-1.pdf, pages 265–272. The eight-page paper is dated 28 June 2011 and covers Mathematics and Mathematics & Statistics Part A.

The department's answer-release policy excludes ordinary odd years. Bounded exact-paper searches found no matching full or selected answer advertisement, so no parts are skipped. All printed parts and their surrounding unnumbered requests are answered below.

Source release: Oxford examination archive, member FOI-20210708-1 - Data/4302.pdf. The cover prints formal code 4302, paper label AC2, the title “Algebra, Analysis and Differential equations II”, and Tuesday 19 June in Trinity Term 2012.

Answer availability checked on 28 October 2026: a bounded search of official Oxford sources found no advertisement of complete or selected-part solutions for this exact paper. The general advertisement of even-year solutions dating back to at least 2016 does not establish coverage of 2012.^[ref]
