Crossword Genius

No rating could be so uneducated (8)

Ross

I believe the answer is:

ignorant

'uneducated' is the definition.
(similar in meaning)

'no rating could be' is the wordplay.
'could be' indicates an anagram.
'no'+'rating'='norating'
'norating' with letters rearranged gives 'IGNORANT'.

'so' is the link.

(Other definitions for ignorant that I've seen before include "Ill-mannered" , "Illiterate - unaware" , "Unaware, uninformed" , "Crass" , "Without knowledge" .)

I've seen this clue in The Guardian.
