Receive poor grade in a prestigious university (5)
I believe the answer is:
admit
'receive' is the definition.
(I've seen this before)
'poor grade in a prestigious university' is the wordplay.
'poor grade' becomes 'D' (an exam result).
'in' means one lot of letters goes inside another.
'prestigious university' becomes 'mit' (Massachusetts Institute of Technology. I am not sure about the 'prestigious' bit.).
'a'+'mit'='amit'
'd' placed inside 'amit' is 'ADMIT'.
Can you help me to learn more?
(Other definitions for admit that I've seen before include "Stop being obstructive" , "Fess up" , "Recognise" , "Allow to enter; own up" , "Confess - acknowledge" .)
