I just had a quick look on the new OCR spec (it's still just a draft but it's
here if you're interested) and if you chose Spanish, the speaking you'd have to do looks pretty reasonable to me
You get 15 minutes to prepare two cards then discuss them. So it's not that different from mine, just you get a slightly shorter time to prepare but then you can see
all of what you'll be asked questions based on before you go in.
No controlled assessments, just 3 exams - listening/reading, writing, speaking. Not sure about OCR but for my listening, we get to control it individually so you can pause and rewind as many times as you like (aka hear a word, pause, write it down, repeat for next word
).
Your AS content doesn't seem all that different from my A2. You'd get to study a film or a book/play, which is so fun! I haven't done English lit since Y11 so was pretty worried but it's the best part of the subject
Seriously though, choose the subject which you think you'd enjoy more. I'm over here forcefully advocating Spanish but if you think Physics would be better for you, then take it.
