College and University

check whether there are subject requirements on the entry requirements pages of the universities that you want to apply to. most unis don't have any required subjects for archaeology so you should study what you're most interested in and what will get you the best grades, but it's best to check for unis you're interested in

Check the entry requirements carefully on each individual course page - they will all be slightly different - check both A levels and GCSEs.
Some examples :
York - https://www.york.ac.uk/study/undergraduate/courses/ba-archaeology/
Cardiff - https://www.cardiff.ac.uk/study/undergraduate/courses/course/archaeology-ba
Nottingham - https://www.nottingham.ac.uk/ugstudy/course/Archaeology-and-Classical-Civilisation-BA
Bristol - https://www.bristol.ac.uk/study/undergraduate/2022/anthropology/ba-arch-anth/
