Is a Training Class or Family Teacher Necessary?

More and more middle school students are going to all kinds of training classes or having family teachers on the weekend. There are two different viewpoints about it.
Some people believe that it is necessary for students to have training classes or family teachers on the weekend. They hold that view for the reason that learning knowledge from teacher is better than learning by themselves. What's more, it can strengthen the knowledge which is learned from the classes. Moreover, it can lean more things too.
However, others think that it is unnecessary to do that. To begin with, it is easy for us to develope a bad habit of always depending on others. Besides, students are in need of rest. Finally, some training classes or family teachers are just there to make money.
In my opinion, I agree to the thought that it is unnecessary for us to do that, therefore, the latter is surely a wise choice for me.
