Collected university certificate with marks on the side? (9)
I believe the answer is:
graduated
This clue is a double definition.
'collected university certificate' is the first definition.
(university graduates collect degree certificates)
'with marks on the side?' is the second definition.
(as in a device marked with units of measurement)
(Other definitions for graduated that I've seen before include "Obtained a university degree" , "Received a degree" , "Successfully completed a degree course" .)
