Study features at college (3,2)

I believe the answer is:

mug up

I'm a little stuck... Click here to teach me more about this clue!

'study' is the definition.
(I know that mug up is a more specific form of study)

'features at college' is the wordplay.
'features' becomes 'mug' (I can't justify this - if you can you should believe this answer much more).
'at college' becomes 'up' ('up' can mean at university).
'mug'+'up'='MUG UP'

Can you help me to learn more?

(Other definitions for mug up that I've seen before include "revise intensively" , "Swot hard" , "Learn subject rapidly" , "Study intensively" , "Learn quickly (for exam)" .)

I've seen this clue in The Times.
