University class? Crashing out in examination (8)
I believe the answer is:
tutorial
'university class?' is the definition.
(type of academic class)
'crashing out in examination' is the wordplay.
'crashing' is an anagram indicator.
'in' is an insertion indicator.
'examination' becomes 'trial' (I've seen this before).
'out' anagrammed gives 'uto'.
'uto' put into 'trial' is 'TUTORIAL'.
(Other definitions for tutorial that I've seen before include "Period of individual instruction" , "Rail tout (anag)" , "University lesson" , "Session with a private instructor" , "University study period" .)
