What language should I study Watch
Seriously though, if you want to be an MFL teacher and are already taking Spanish, the next best option should honestly be French. I’m a B1 Level French learner at high school, and it’s honestly not that difficult. Practice is the key
At the end of the day, everything's fluid. Maybe your experiences up until now have marred your vision of French but it really is a superb language to learn and it complements Spanish very well. I'd highly recommend it. Otherwise, maybe you could pick up a different language like Portuguese, Italian, German, Japanese, Chinese Mandarin, Russian or Arabic. For all of the languages I've listed (even including German sometimes), universities generally don't need an A level to learn it at degree level. Ergo, you could apply for Spanish + another language at university without doing the other language at A level. That said, for degree level French, you'd definitely need A level French.
