Can we use "accurate" to describe a person? Defenitions I've looked up in dictionaries refer to things, information etc.
As Khosro said, you can be accurate in something. To say that a person is just accurate is uncommon.
Other members can help you to find better words for it, if there are any.
Furthermore, take a look at this sentence:
"My aim wasn't very good and the ball went over the fence."(Macmillan dictionary)
