Face-to-face exam (4)
I believe the answer is:
oral
'face-to-face exam' is the definition.
(I've seen this in another clue)
This is the entire clue.
(Other definitions for oral that I've seen before include "By word of mouth, say exam" , "Relating to speech" , "Exam using speech" , "Spoken exam" , "Relating to the mouth - exam" .)
