See terms properly organised for academic period (8)
I believe the answer is:
semester
'academic period' is the definition.
(I've seen this before)
'see terms properly organised' is the wordplay.
'properly organised' is an anagram indicator.
'see'+'terms'='seeterms'
'seeterms' anagrammed gives 'SEMESTER'.
'for' is the link.
(Other definitions for semester that I've seen before include "Steers me towards university term" , "Met seers during university term" , "Half-year division of an academic year" , "College spell" , "half-year course of study" .)
