Graduate fixes tent with piece of wood (6)
I believe the answer is:
batten
'piece of wood' is the definition.
(I've seen this before)
'graduate fixes tent' is the wordplay.
'graduate' becomes 'BA' (someone with a Bachelor of Arts degree).
'fixes' indicates anagramming the letters (I've seen 'fixed' mean this).
'tent' with letters rearranged gives 'tten'.
'ba'+'tten'='BATTEN'
'with' is the link.
(Other definitions for batten that I've seen before include "Gain nourishment" , "Wood strip; fasten for advantage (on)" , "Close securely, say the hatches" , "Strip fixed to something to hold it firm" , "Fastener for tarpaulin" .)
