    The most important thing to keep in mind when going into high school is to be yourself. Besides, I don't know what your middle school was like, but high school teachers will not care about things such as how much homework you already have in one night. It's best to just learn to deal with things and manage your time wisely so you can achieve everything you need to.

    I think almost every kid feels both nervous and excited before their first day. You will probably love it. I know I did. You should join some sports or activities that will make your high school experience more enjoyable.

    Good luck!

    When I started high school I was really nervous too, especially since I had been homeschooled all through middle school and didn't really know anyone. I suppose the best advice would be to just relax. The first couple of days can be a little bit hard, but things will become easier before you know it.

    I am not going to lie. The first day is kind of frightening. But you'll get used to it. Don't be afraid of anyone; upperclassmen will pick on you more if you let them know you're afraid. Just take it easy. Making some friends and staying with them will greatly help you get used to high school quickly. After the first week it's really not bad at all. Don't worry.

    Bill,a 13-year-old boy, thought he had grown up to be a man. But his parents told him, "You won't be a real man until you begin to think about helping others."
    One moming, his parents gave him some money to buy some milk. Outside a shop he saw a homeless old~man who looked very sick. Bill went to him and asked. "what's wrong with you?"
    The old man answered, "I'm hungry,I haven't had any food for two days".
   “Let's go to the restaurant."
    When they got there, Bill asked the waiter to bring out bread and coffee to the old man. The old man finished the meal quickly. Afier the waiter took away the plate and the cup, the old man said, "Sorry for giving you too much trouble. I'm fine now. I'Il never forget your kindness! You're a very good young man."
    Bill was happy when he heard this. Just when he wanted to pay for the meal, the waiter came.To their surprise, Bill and the old man leamed that their food was free because it was the birthday of the boss, and they were the first customers that day.
