Examination ordeal (4)
I believe the answer is:
test
I believe this is a double definition.
'examination' is the first definition.
(I know that examination can be written as test)
'ordeal' is the second definition.
(a testing situation)
(Other definitions for test that I've seen before include "Short exam" , "Trial; cricket match" , "Assess - examination" , "tax" , "Trial; exam" .)
