Answer:
relax our mind first
Explanation:
because most people will get panicked before exams and we need to have a peace mind before studying or doing revision and all that .
when we're very nervous , it's hard to concentrate at what we're studying and we may failed the test .
just take a deep breath and keep this in our mind "i can do this i must study well so i will be able to get a job that i want one day"
