Exam or quiz (4)
I believe the answer is:
test
I believe this clue is a double definition.
'exam' is the first definition.
(I know that exam can be written as test)
'quiz' is the second definition.
(I know that quiz can be written as test)
(Other definitions for test that I've seen before include "Experiment" , "Cricket match; try" , "Trial - big match" , "Trial; exam" , "Trial; cricket match" .)
