Dear Jenny,
I’m so worried when I see that you’re not a little tired and nervous about the coming College Entrance Examination; Here is some advices to help you prepare the coming exam. Have enough sleep, whatever much work you have to do，or you’ll feel sleepy on an occasion in class. A balanced diet will certainly help a lot. Having more fresh fruit and vegetables every day are good for you. Which you know, a proper method of learning will enable you to learn more and faster. To get better results, that is wise to be attentive and make every effort to gain knowledge. And you were supposed to review your notes taking down after class every day. Always remember to stay happily and optimistic so that you can be energetic while doing the revision. I hope you’ll no longer feel tired and nervous.
Best wishes.
