One possible version: First of all, you should believe in yourself. Nothing is impossible for a willing heart. And you should always be active in class. When you are at home, remember to go over what you’ve learned before doing homework. You should also learn to help each other. Two heads are better than one, you know. And remember to do some sports to make yourself healthy and smart. Last but not least, you should always remember that your teachers are willing to help you any time. So if you have problems, you can turn to them for help.
