Student doing badly with golf and getting stuck (7)
I believe the answer is:
lodging
'getting stuck' is the definition.
(getting lodged is getting stuck)
'student doing badly with golf' is the wordplay.
'student' becomes 'l' (as in L-plates for learner drivers).
'badly' indicates anagramming the letters.
'with' says to put letters next to each other.
'golf' becomes 'g' (phonetic alphabet: alpha, bravo, charlie etc.).
'l'+'doing'='ldoing'
'ldoing' anagrammed gives 'lodgin'.
'lodgin'+'g'='LODGING'
'and' acts as a link.
(Other definitions for lodging that I've seen before include "Depositing" , "Temporary accommodation" , "being fixed" , "Place to stay" , "where one lives" .)
