At college just standing (7)
I believe the answer is:
upright
'standing' is the definition.
(I've seen this before)
'at college just' is the wordplay.
'at college' becomes 'up' ('up' can mean at university).
'just' becomes 'right' (associated in meaning).
'up'+'right'='UPRIGHT'
(Other definitions for upright that I've seen before include "In an erect position" , "Key item" , "Joanna" , "Erect - post" , "Erect - honest" .)
