Study: Keeping pace (步伐) with teachers is a good way to study. Teachers are experienced and their plans are systematic (系统的). But remember to work in a way that suits you. It’s also important to learn from past mistakes. Keep a notebook to make a record of the mistakes you make – it’ll help you avoid making the same ones later.

Friendship: This time of life may be hard, but you’re not alone. You may be busy studying, but you can show you care by calling your friends or sending a short message. Don’t let your friendships die. Some boys and girls in my class were in love, but I’d advise against a relationship at this stage.

Huanggang High School, Hubei

Health: It’s as important to live well as it is to study well, I think. I went to bed no later than 11:30 pm. It put me in the right mood for the next day. I didn’t follow a special diet (饮食), but I did make sure I ate a nutritious (有营养的) breakfast each day.

Yantai Economic and Technological Development Zone Senior High School, Shandong

Relaxation: The person who plays well, studies well. Having a lot of schoolwork doesn’t mean having to give up on every other activity. I played basketball or took a walk to relax when I felt tired. Time out is not a waste of time but helps you study more efficiently (高效地).
