Hi! You can definitely do Latin post A-Level in combination with Spanish ab initio.
That's the short answer! I've run through roughly what you can expect from the course structure below after the first year (where it's a lot less prescribed) - language courses can vary quite a lot between universities. I did French plus ab initio Spanish myself - an ab initio language is a really great opportunity to learn a new language much more quickly than school. Note: exact paper choices available can change year to year - this is just the current options.
Second YearIf you do Spanish ab initio, then B1 and B2 are Use of Spanish, Translation & Oral - which is the language papers first years with A-Level Spanish do (so in your second year, you join classes with first years with the A-Level).
You would then *have* to offer one of the following papers:
SP 3 - Medieval Iberia, early modern Spain and Latin America
SP 4 - Modern Spanish culture and history
SP 5 - Latin-American culture and history
SP 11 - The Hispanic languages (linguistics-related)
But you could also (in theory) do CS1 - Romance Languages (linguistics) or CS 6 on European Film, GR 3 - Introduction to Modern Greek, SP6 - Introduction to Catalan or PG 3 - Introduction to Portuguese (you can only do one of the intro to X language papers though). You could also offer any of these CS (comparative studies) or intro papers in your fourth year.
You
have to do GL16 - Latin Literature. Then your final paper could be another one of the above, or one of the classics papers listed. GL22 (translation into Latin) you can add on as an extra if you wish but you don't have to.
Third & Fourth YearYou'd spend your year abroad in a Spanish-speaking country, and then you would do MML papers in your fourth year. Alongside the language papers C1 and C2 + oral exam (and the
Year Abroad Project during your YA), you then do
three papers - two of these can be 'borrowed' from other faculties including
Classics, so you could insert that back into your course there, or ditch it altogether if you so wished.
