Concerns about interrupting in exams (9)
I believe the answer is:
interests
'concerns' is the definition.
(interesting is a kind of concerning)
I can't explain the rest of the clue.
Can you help me to learn more?
(Other definitions for interests that I've seen before include "Hobbies or preoccupations" , "Financial involvements or matters of curiosity" , "Pastimes or concerns" , "Appeals, fascinates" , "is fascinating" .)
