How to NOT loss focus during exams

Exam pressure is huge. But it is really huge? In my opinion, NO, never. It seems huge because there are too many empty noises. Everyone has an opinion around you,  your exams,  your career.
The problem area is, we take empty noises seriously, every empty noise bothers us.
Teacher: Exams are coming,  you are poor in language.
Parents: Will you pass the exam with good grade?
Friends: How much you will score?
Siblings: You don't study hard...
Neighbors: What is your career plan?
All these people are not your enemy.  In fact they are the first who come to give you courage in hard times.
Their problem is not you,  your grade or career. Exam is a talking point, it makes news and people love to talk.
The problem is when we hear empty noises we loss control over us.
Be like a lorry driver. Go highway and observe how a lorry driver do not change lane despite too many horns blown into  ears.
A good driver always keep the vehicle on track and let the other vehicles pass when there is room to give a pass.
Dictionary has given us,  two beautiful words to not loss focus, 'excuse me'.
