Regarding new student curriculum; it's just a slightly updated revision of what they already know (9,6)
I believe the answer is:
refresher course
'just a slightly updated revision of what they already know' is the definition.
The definition suggests an adverb but the answer is not.
'regarding new student curriculum' is the wordplay.
'regarding' becomes 're' ('re' means regarding or about).
'new student' becomes 'fresher' (I've seen this before).
'curriculum' becomes 'course' (I've seen this before).
're'+'fresher'+'course'='REFRESHER COURSE'
'it's' is the link.
Can you help me to learn more?
(Other definitions for refresher course that I've seen before include "sweet group?" , "Training" , "further education?" , "it helps you get up to speed" , "study update" .)
