Here are some excerpts from the 2024-2025 admissions cycle report on Human Sciences:
In Human Sciences, 167 (161 in 2023) candidates applied to Oxford; 105 (95 in 2023) of
those were shortlisted following the guidelines agreed among the colleges. The outcome
was that 36 (34 in 2023) offers were made, all for 2025.
For Human Sciences, the large numbers applying overall entail that it is not possible to
interview all candidates: only a proportion of candidates can be summoned for interview –
just over 60% overall this year. Grounds for not summoning include: less good results in
official examinations (especially GCSE); less good results predicted for A level and/or other
impending examinations; and relatively low results in the TSA.
My advice is to hit the TSA prep hard and do your research on the interview process to prepare for that as well. Also give some thought on who your UCAS “referee” will be. They need to be able to write an “Oxford style” letter of recommendation for you which is much different from a traditional US style letter.
Additionally, only nine Oxford colleges offer the Human Sciences course, so you will need to give some thought on where to apply. I would recommend against an open application as two of the nine are Harris Manchester and Regents Park which are “different” from traditional oxford colleges.
