Variable IQ reflected after taking in university pub event? (4)
I believe the answer is:
quiz
'pub event?' is the definition.
(I've seen this in another clue)
'variable iq reflected after taking in university' is the wordplay.
'variable' becomes 'z' (algebra).
'reflected' says the letters should be written in reverse (letters reflected back).
'after taking in' indicates putting letters inside.
'university' becomes 'U' (abbreviation for university).
'z'+'iq'='ziq'
'ziq' reversed gives 'qiz'.
'qiz' going around 'u' is 'QUIZ'.
(Other definitions for quiz that I've seen before include "Question" , "Series of testing questions" , "popular in many pubs" , "Pump" , "Panel game" .)
