Eight heartless school assessments: papers turned over with mild revulsion (8)
I believe the answer is:
distaste
'mild revulsion' is the definition.
(I've seen this before)
'eight heartless school assessments papers turned over' is the wordplay.
'heartless' means to remove the middle letters.
'school assessments' becomes 'sats' (I am not sure about this - if you are sure you should give a lot more credence to this answer).
'papers' becomes 'ID' (identifying documents are one's 'papers').
'turned over' says the letters should be written backwards.
'eight' with its centre taken out is 'et'.
'et'+'sats'+'id'='etsatsid'
'etsatsid' reversed gives 'DISTASTE'.
'with' acts as a link.
Can you help me to learn more?
(Other definitions for distaste that I've seen before include "lack of relish?" , "Antipathy, aversion" , "Feeling of dislike - unsavoury?" , "Not liking" , "Loathing" .)
