It's a new way to take exams (3)
I believe the answer is:
sit
'way to take exams' is the definition.
I can't judge whether this definition defines the answer.
'it's a new' is the wordplay.
'a new' is an anagram indicator.
'its' with letters rearranged gives 'SIT'.
Can you help me to learn more?
(Other definitions for sit that I've seen before include "Take a pew, an exam" , "Be seated" , "Take a chair" , "(Of bird) stay on nest" , "I sell badly the cotton yarn" .)
