My clue shocked college (6)
I believe the answer is:
lyceum
'college' is the definition.
(I've seen this before)
'my clue shocked' is the wordplay.
'shocked' is an anagram indicator (letters are shocked or disrupted).
'my'+'clue'='myclue'
'myclue' anagrammed gives 'LYCEUM'.
(Other definitions for lyceum that I've seen before include "Aristotle's garden" , "Aristotle's school" , "Garden in Athens where Aristotle taught" , "Ancient Greek school" , "French school or concert-hall" .)
