Soon you’ll be studying in the UK, but English isn’t your native language. If it’s something you’re worried about, this article is for you.
First of all, if you’re able to read this text without major problems (and dictionaries), you should be fine.

It doesn’t mean you’re not encouraged to improve your language skills!
