Quietly claim university raised result (6)
I believe the answer is:
upshot
'result' is the definition.
(synonyms)
I don't understand the rest of the clue.
Can you help me to learn more?
(Other definitions for upshot that I've seen before include "Eventual outcome or conclusion" , "anti-aircraft fire?" , "Outcome, consequence" , "increased exposure" , "skier" .)
