Rising hack writing for papers (5)
I believe the answer is:
exams
'papers' is the definition.
(I've seen this before)
'rising hack writing' is the wordplay.
'rising' says the letters should be written backwards (going up in a down clue).
'hack' becomes 'axe' (axing is a kind of hacking).
'writing' becomes 'ms' (abbreviation for manuscript).
'axe' backwards is 'exa'.
'exa'+'ms'='EXAMS'
'for' is the link.
(Other definitions for exams that I've seen before include "Set of exercises evaluating knowledge (abbr)" , "finals?" , "papers" , "More than one test" , "Knowledge tests" .)
