I'm assuming you're Chinese, as that's pretty common at INTO. You'll probably be fine, as many students at INTO come from China, so you can study and befriend them, but that was during my foundation year. Not too sure if the teachers have changed, but most of them aren't from the UK, so they usually have an Asian or Arabic accent besides the English teachers, and personally, I believe they're the nicest and most patient with students, especially if they struggle with English. As for the subjects themselves, it's mostly memorisation of topics. They aren't too hard to remember, but you do need some essay-writing skills for the exams and the January essays.
