Gather together in circle at college (5,2)
I believe the answer is:
roundup
'gather together' is the definition.
(I've seen this before)
'circle at college' is the subsidiary indication.
'circle' becomes 'round' ('round' can be a synonym of 'circle'**).
'at college' becomes 'up'.
'round'+'up'='roundup'
'in' is the link.
(Other definitions for roundup that I've seen before include "Gathering of cattle or summary" , "Collection of facts" , "Gather together" , "Summary (of events)" , "Gather into one place, animals or people" .)
