Great explanation, thanks!

No, that's OK.  We do use the term 'oral' to define a particular type of exam - an oral assessment or an oral test, for example. So you might say 'I got my exam results yesterday. I got a good mark in my written exam, but not such a good one in my oral'. Here 'my oral' refers to a specific test in spoken English.

'My oral' does <em>not </em>refer to a person's general skill in speaking a language - that's what sounds strange to us.  In this situation you'd say 'my speaking' or 'my spoken English'.

What about 'Oral Assessment'? Does that sound odd?

Just one word of advice, Andy. Only Chinese people use the word 'oral' in this way. 'I'd like to practise my English oral'  sounds very odd to native English speakers. We don't say this.

The normal expression is 'spoken English':  'I'd like to practise my spoken English' or 'I'd like to practise my speaking skills.'

Good luck with your studies!

Thank you all, I'm glad to hear your voice.
