Given position in class: Greek reportedly helped (6)
I believe the answer is:
graded
'greek reportedly helped' is the definition.
I can't judge whether this definition defines the answer.
'given position in class' is the wordplay.
'given' is a charade indicator (letters next to each other).
'position in' becomes 'd' (I can't explain this - if you can you should give a lot more credence to this answer).
'class' becomes 'grade' (synonyms).
'd' after 'grade' is 'GRADED'.
Can you help me to learn more?
(Other definitions for graded that I've seen before include "Gave mark to (student's work)" , "Classified" , "Sorted by quality or rank" .)
