Goodness gracious, having to get round exam on modern technology! (8)
I believe the answer is:
morality
'goodness' is the definition.
(thesaurus)
'gracious having to get round exam on modern technology' is the wordplay.
'gracious' becomes 'my' (I've seen this in other clues).
'having to get round' means one lot of letters goes inside another.
'exam' becomes 'oral' (oral exam is a kind of exam).
'on' is a charade indicator (letters next to each other).
'modern technology' becomes 'it' (Information Technology).
'oral'+'it'='oralit'
'my' going around 'oralit' is 'MORALITY'.
(Other definitions for morality that I've seen before include "Concern with the distinction between right and wrong" , "Ethical behaviour" , "Ethics" , "Good sense" , "Behaviour in terms of right and wrong" .)
