Postgraduate entrance examination is a way for college students to improve their academic qualifications, and it is also an excuse to escape from entering the society. I have met too many people around me, from choosing a school to buying books to preparing for exams to giving up exams. Giving up may be an excuse to give up in an instant, or there may be no reason to insist. However, in the library, what you see is the hard work of everyone. The long queue at seven o'clock in the morning, the classmates standing in the dark corridor for breakfast and the classmates standing outside the rooftop on the third floor below zero all gave me the motivation to study like them. It's not hard to stick to it. Look at the classmates who work as hard as themselves and ask yourself, why not work hard?
