He acts wrongly and passes exams unfairly (6)
I believe the answer is:
cheats
'passes exams unfairly' is the definition.
I can't judge whether this definition defines the answer.
'he acts wrongly' is the wordplay.
'wrongly' is an anagram indicator.
'he'+'acts'='heacts'
'heacts' anagrammed gives 'CHEATS'.
'and' acts as a link.
Can you help me to learn more?
(Other definitions for cheats that I've seen before include "Chaste (anag.)" , "Fixes" , "Swindles, defrauds" , "Tricks or swindles" , "Frauds" .)
