Not hard to be even less exam shy! (4)
I believe the answer is:
easy
This might be a double definition.
'not hard' is the first definition.
('easy' is the opposite to 'hard')
'even less exam shy' is the second definition.
'easy' can be an answer for 'even' (thesaurus). I am not sure about the 'less exam shy' bit.
'to be' is the link.
Can you help me to learn more?
(Other definitions for easy that I've seen before include "... Rider (film)" , "Undemanding" , "for a piece of cake" , "Posing no difficulty" , "Comfortable" .)
