In addition, there are a couple of university guides. I looked up the Guardian’s league tables , and they, for ex., list about 25 universities that offer Classics or Ancient History degrees. Just work your way through the list, a few at a time, and look for the ones that: (a) appeal to you as a university overall, (b) you like the structure of the course design (look at this carefully), and (c) also seem like they have entry tariffs you meet (this is often under “international”).
Make a chart or spread sheet to record your research. If you’re not sure if your qualifications are a good fit, you can just contact the university and ask. It’s a little tedious, but I think this is the best way.
