Review the evidence of problem at university (3,2)
I believe the answer is:
sum up
'review the evidence' is the definition.
(I've seen this before)
'problem at university' is the wordplay.
'problem' becomes 'sum' (arithmetic problem**).
'at university' becomes 'up'.
'sum'+'up'='SUM UP'
'of' acts as a link.
(Other definitions for sum up that I've seen before include "Make final precis of evidence" , "Recapitulate (in court)" , "(Of a judge) review the evidence" , "Of a judge, give the main points of the evidence for jury" , "Conclude" .)
