Not too difficult as exams go and fair (8)
I believe the answer is:
passable
'fair' is the definition.
(synonyms)
'not too difficult as exams go' is the wordplay.
I cannot really see how this works, but
'as' is within the answer.
This explanation may well be incorrect...
'and' is the link.
Can you help me to learn more?
(Other definitions for passable that I've seen before include "Fair" , "Fairly good but not outstanding" , "examinations should be!" , "Good enough to be acceptable" , "OK" .)
