A point to study? Get away with you! (5)
I believe the answer is:
scram
'away with you' is the definition.
I can't judge whether this definition defines the answer.
'a point to study?' is the wordplay.
'a point' becomes 'S' (South).
'to study?' becomes 'cram' (cramming is a kind of studying).
's'+'cram'='SCRAM'
'get' acts as a link.
Can you help me to learn more?
(Other definitions for scram that I've seen before include "Leave quickly" , "Shoo!" , "Bolt" , "on your bike!" , "Go away quickly" .)
