About Self-study（1） More and more middle school students are going to all kinds of training classes or having family teachers at the weekend. There are two different viewpoints about it. Some
people think that it is necessary. First, they can learn better with the help of the teachers than by themselves. Second , they can strengthen what they learn in class. Third , they can get more useful things in those classes. However, other people insist that it is not necessary. For one thing, students will not listen carefully in their normal classes if they can get the same knowledge in training classes. For another thing, most senior students haven’t enough time to rest. What’s worse, the purpose of most of the training classes and family teachers is to earn money. In my opinion, a training class or family teacher is not necessary. We can study well at school if we work hard. About Self-study（2） Self-study is a good way of improving our knowledge of things. Some of the great scientists and lecturer couldn't afford to go to school so they just studied at home without anybody's help. Sometimes self-study could be more affective then going to schools and listen to teachers telling you what to do, but sometimes it will be better to learn in schools to further knowing what’s going on. As adult students in a TV University, self-study becomes very important. According to me, there are several pieces of tips of self-study. First, I always make a study plan in the beginning of a new semester. Second, preview every unit before the lesson. Third, try to finish the homework after class. Fourth, go over what I have learnt in class regularly at home. Without review, you will absolutely forget what you’ve learnt as quickly as possible. So reviewing is helpful in understanding and memorizing what you’ve learnt. About Self-study（3） Self-studying can enhance students' memory more effectively, and cultivate a good hobby of independent thinking. However, everything has its two sides, there're also something negative in self-study ,self-study might cost much more time when you meet a difficult problem than discuss it with you classmates. All the factors about leads to a conclusion that there're so many ways to study,which is the best depends on yourself.
