Passage about university examination (5)
I believe the answer is:
audit
'examination' is the definition.
(I've seen this before)
'passage about university' is the wordplay.
'passage' becomes 'adit' (adit is a kind of passage).
'about' is an insertion indicator.
'university' becomes 'u'.
'adit' going around 'u' is 'AUDIT'.
(Other definitions for audit that I've seen before include "Financial review" , "Roman Aquae Sulis" , "HMRC inspection" , "Examination of accounts" , "Go over" .)
