'student a buzzer-beater?' is the definition.
I can't judge whether this defines the answer.

'crafty last-minute' is the wordplay.
'crafty' becomes 'fly' (fly can mean shrewd or crafty).
'last minute' becomes 'swatter' (I can't explain this - if you can you should believe this answer much more).
'fly'+'swatter'='FLYSWATTER'
