Crossword Genius

Wrong grade needing correction, shocked (8)

Ross

I believe the answer is:

outraged

'shocked' is the definition.
(I've seen this before)

'wrong grade needing correction' is the wordplay.
'wrong' becomes 'out' (eg a calculation might be 'out').
'needing correction' indicates anagramming the letters (I've seen this in other clues).
'grade' anagrammed gives 'raged'.
'out'+'raged'='OUTRAGED'

(Other definitions for outraged that I've seen before include "caused offence" , "mad" , "Appalled, incensed" , "Violated" , "in high dudgeon" .)

I've seen this clue in The Telegraph.
