Soon-to-be graduate (6)
I believe the answer is:
senior
'soon-to-be graduate' is the definition.
(I've seen this in another clue)
This is the entire clue.
(Other definitions for senior that I've seen before include "Pupil in a higher form" , "Denoting older people" , "Higher in status" , "Superior - elder" , "Elder (of two)" .)
