English students from less privileged backgrounds and state, rather than private, schools remain significantly under-represented at high-status universities. There has been little work to date on the role of A-level subject choice, as opposed to attainment, in access to university. Using linked administrative data for three recent cohorts of English entrants to UK universities, I examine the relationship between league table score of university attended and A-level subject choices, using a taxonomy of A-levels categorised according to their published efficacy for Russell Group university admission as "facilitating, useful", or "less suitable". I further examine the relationship of three "less suitable" A-levels with league table score of university for related degree courses commonly leading to professional business careers (accountancy, business, and law). Holding more facilitating A-levels is associated with attending a higher ranked university overall, even controlling for degree subject, and the converse is true for "less suitable" subjects. The heterogeneous relationships of professionally-related A-level subjects with university ranking make decision-making for aspirational 16-year-olds problematic: an apparently sensible subject choice for students wishing to prepare for a professional career may, in fact, put them at a disadvantage.
