Old map I revised for academic qualification (7)
I believe the answer is:
diploma
'academic qualification' is the definition.
'diploma' can be an answer for 'qualification' (type of academic qualification). I am not certain of the 'academic' bit.
'old map i revised' is the wordplay.
'revised' indicates anagramming the letters.
'old'+'map'+'i'='oldmapi'
'oldmapi' is an anagram of 'DIPLOMA'.
'for' is the link.
Can you help me to learn more?
(Other definitions for diploma that I've seen before include "Certificate of education" , "Document conferring a qualification" , "Paper showing examination success" , "Certificate of proficiency" , "What a student seeks" .)
