There is an opinion that students should focus on only one subject. In my opinion, this is a well-justified view for several key reasons.
One of these reasons is that studying many subjects helps students gain more knowledge. It allows them to understand the world better and know everything in such a way. For example, science teaches how things work, while history helps students learn about the past. This makes education more complete and difficult to lead in every sphere.
Another important reason is that different subjects help students find their interests. If students study only one subject, they may not discover as much information. When they know and try to learn every single subject, in the future it will be easier to find a job; while others study only one subject, it will be a problem for them. For instance, in ancient Kazakh times, many well-known poets such as Abai Kunanbaiuly, Mirzhakyp Dulatuly and others knew everything, studied every subject, and even other languages from their childhood, and this helped them to open alash ordasy.
If there were no such kind of poets, in these times maybe there wouldn’t be Kazakh people.
In conclusion, I fully disagree with the idea that students have to study only one subject, because it’s not correct for our lives; we have to study and learn all the things.
