Starting high school means many changes in your life. Most teenagers look forward to the first day of high school, but still feel a little bit nervous. In order to make your high school life easier, you can follow these tips.

Learn all you can about your first day before the first day. Take part in some activities that are held at the school for new students to know the school better. If parents are invited to these activities, take yours with you. Carefully look over all the materials you receive. Be sure you know where the school’s buildings are.

Get the things you will need for class. Buy the things suggested on your teachers’ supply lists and place your materials for each class separately.

Keep up with your high school workload(工作量). If you find you’re not doing well in a subject, make use of after-school study groups or ask your teacher to help you with your schoolwork. Consider private tutoring to get you through a difficult time.

There’re more extracurricular(课外的)activities in high school than in middle school, such as clubs, music and theater groups, student government, and sports teams. Make friends and be seen at such school activities. Join a club or other organizations to meet people and develop friendships. Ask someone in school activities if you don’t know how. This is a good time to do what you like doing and an opportunity to try new things. Who said school has to be all work and no play?

Since you’ll attend more activities in high school than in middle school, you’ll have to learn how to manage you time…
