Hi there,

Is it possible to use any adjective to describe one's behaviour or even facial gestures when we know these could impress the interviewer, say, in an speaking test (resulting in a better mark)?

'...even the body language you use and your facial gestures could be ................. in/on the mark!'

I think it's possible to say it will impress the interviewer, but what if I want to use the word mark or score? Could any adjective like 'impressive' or 'influential' fit in the blank above?
