Learn With A Teacher Or Ourselves

Today, some people learn with a teacher, and other people learn alone. I think people learning with a teacher is better than people learning alone. Because, If we study alone, we can't concentrate and we can't study well. I think in order to learn, having a teacher is a must.
First, If we study alone, we can't concentrate. If we don't concentrate, our teacher will scold us. Like this, A teacher interferes with us. So we can study as we shoud. I study with a teacher. So I can learn as I should. I think If we want to learn as we should, we must learn with a teacher.
Second, If we study alone, we can't study well. If we learn with a teacher, we can't study well. Because, we can't study. In this way, teachers can explain subject study. So we need teacher, when we study. I study with a teacher. So I can ask my teacher, and I can receive explanations by a teacher.
I think people learning with a teacher is better than people learning alone. Because, If we study alone, we can't concentrate and we can't study well. If we don't concentrate, a teacher can scold us. If we can't study well. Teachers explain about difficult subjects think we need a teacher.
