Looking after students having done exam (8)
I believe the answer is:
pastoral
'looking after students having' is the definition.
I can't tell whether this definition defines the answer.
'done exam' is the wordplay.
'done' becomes 'past' (both can mean finished).
'exam' becomes 'oral' (spoken academic test).
'past'+'oral'='PASTORAL'
Can you help me to learn more?
(Other definitions for pastoral that I've seen before include "Well-known symphony" , "Portraying romanticised country life" , "Country style" , "Depicting rural life" , "Letter to church members" .)
