Quits, accepting last of test results (6)
I believe the answer is:
events
'results' is the definition.
(I know this)
'quits accepting last of test' is the wordplay.
'quits' becomes 'evens' (I've seen this before).
'accepting' indicates putting letters inside.
'last of' says to take the final letters.
The last letter of 'test' is 't'.
'evens' going around 't' is 'EVENTS'.
(Other definitions for events that I've seen before include "promotions" , "Planned social occasions" , "Episodes" , "Things taking place" , "They happen at a given place and time" .)
