Another thing, for language applicants especially. I've noticed when talking to people starting uni to study languages, they expect to watch the occasional foreign film, go on their year abroad and just swan around the odd café and come back fluent. A lot of people fail to realise just how much work it actually is, despite the low numbers of contact hours. You'll get crazy amount of vocab every week, and you'll have to learn even more in independent study. Also, you'll cover so many grammar points in a very short amount of time, so there's that to stay on top of too. Culture modules also require a lot of reading, with around 10 sources to be expected for a 1,500 word essay, and it's common you'll take at least two culture modules a semester.
For the year abroad, it's often the case you'll have to sort out your own accommodation, phone contracts, medical check ups and any necessary resident permits, often in places where little English is spoken. This is incredibly daunting but doable if you did well before you went
Don't mean to scare anyone applying for languages, but it is a lot more intense than people think.
