Ridicules practice exams (5)
I believe the answer is:
mocks
This clue is a double definition.
'ridicules' is the first definition.
(I've seen this in another clue)
'practice exams' is the second definition.
(I've seen this before)
(Other definitions for mocks that I've seen before include "Ridicules" , "practice exams" , "trial examinations" , "Scorns" , "Test examinations" .)
