There are two different viewpoints about it.Possible version:Is a Training Class or Private Teacher Necessary More and more middle school students are going to all kinds of training classes or having private teachers at the weekend. There are two different viewpoints about it.Some think it necessary. Firstly, it's more effective to study with a teacher than by oneself. Secondly, it can strengthen what is learnt in class. Besides, they can learn a lot more. Others think it a waste of time. For one thing, students can easily form the habit of dependence. For another, students need to relax from time to time. What's more, the purpose of many training classes or private teachers is to make money.In my opinion, whether a training class or a private teacher is needed all depends. If you are really very weak in certain subject, maybe it's OK for you. But be sure to choose a good and suitable class or teacher, otherwise it would be a waste of time and money.
