Have you ever wanted to be a college student? If so, then you must know that you have to be a smart student. This means you have to achieve excellent grades in high school. The following tips may be of great help to you. Stop spending most of your free time watching TV or surfing the Internet. Your spare time can be spent in studying and reviewing the knowledge your teacher has already spread. Record important notes that your teacher explains in class. This will help reduce your preparation time for tests., which means you could start studying early. You should also read through your notes carefully because most of the things on your notes are likely to appear on the test paper. Ask your teacher for help if you don’t understand some of the knowledge. Don’t be afraid of asking questions, or you will not get a better understanding of the knowledge. Study for your tests as soon as possible. If you finish it fast, you will have more time to relax and do your favorite things. In addition, waiting until late at night will only make things harder because you may feel tired. Join a tutoring(家教) service near you if you are really serious about your grades. There are many tutoring services and if you can’t find any near you, there are services available to the public on line. Tutoring services can be a great way to get extra help and can be a great way to prepare yourself for the tests.
