Varied resources here to cover French study update (9,6)
I believe the answer is:
refresher course
'study update' is the definition.
(I've seen this before)
'varied resources here to cover french' is the wordplay.
'varied' is an anagram indicator.
'to cover' is an insertion indicator.
'french' becomes 'fr'.
'resources'+'here'='resourceshere'
'resourceshere' anagrammed gives 'reeshercourse'.
'reeshercourse' enclosing 'fr' is 'REFRESHER COURSE'.
(Other definitions for refresher course that I've seen before include "study update" , "further education?" , "Training" , "it helps you get up to speed" , "sweet group?" .)
