to questions you are less confident about. Also time yourself and
mentally have a certain amount of time fixed for answering the questions
and stick to it.

Officer's attitude: Begin to think and behave like an officer. You can
practice by putting yourself in the shoes of an officer every time you
face a situation. This will certainly play a vital role in developing
your personality. Just a word of caution - be sincere when you think and
behave like an officer, because superficiality is not going to pay
here.
Build confidence: Have the confidence that you will clear the CDS
exam. After all the Defence Forces is all about courage and confidence.
So, having a positive attitude will go a long way in ensuring that you
clear the CDS exam.
