Formality over college paper - it's a sweet course (3,5)
I believe the answer is:
ice cream
'a sweet course' is the definition.
'ice cream' can be an answer for 'course' (ice cream is a kind of course). I'm not sure about the 'a sweet' bit.
'formality over college paper' is the wordplay.
'formality' becomes 'ice' (I've seen this before).
'over' says to put letters next to each other.
'college' becomes 'c'.
'paper' becomes 'ream' (I've seen this before**).
'ice'+'c'+'ream'='ICE-CREAM'
'it's' is the link.
Can you help me to learn more?
(Other definitions for ice cream that I've seen before include "Dish" , "chilling creation" , "99, for example" , "Sweet frozen food" , "interval treat required?" .)
