"Please kindly follow the instructions."

What I've noticed to other teachers, when their students are taking a quiz or an examination, they'll say, "KINDLY follow the instructions."

Yes! I should emphasise KINDLY. Instructions are important during an examination because when you don't follow a simple instruction in a quiz, it'll mark wrong.

The word 'Kindly' is used in the sentence like, "KINDLY pick up the pieces of paper," or "KINDLY fall in line outside." In those sentences, Kindly is used to the reciever of the sentence to act properly and not to act too childish. But the term "Kindly" for the sentence, "KINDLY follow the instructions," is not proper. Is there a student in an examination that won't act properly in following the instructions listed in the test paper?
