Got ready for homework -- poor dear! (8)
I believe the answer is:
prepared
'got ready' is the definition.
('prepare' can be a synonym of 'get ready')
'homework poor dear' is the wordplay.
'homework' becomes 'prep' ('prep' can be a synonym of 'homework').
'poor' indicates an anagram.
'dear' anagrammed gives 'ared'.
'prep'+'ared'='PREPARED'
'for' acts as a link.
(Other definitions for prepared that I've seen before include "Made or got ready" , "Ready for action" , "Waiting" , "edited" , "All set" .)
