Проверьте пожалуйста эссе, и исправьте ошибки:
All subjects at school are equally usefull.
Everybody knows that people have various preferences so it is natural that school students want to study the subjects they are interested in. But many teachers are against this, arguing that students must learn all subjects equally.
It seems to me that we need special schools for students, where they can have extra classes in some subjects that are important to their future profession. Besides, students could be allowed to choose the subject they want to study.
Sometimes, we don’t have enough time to learn complex, difficult subjects like mathematics, physics and chemistry I usual schools.
Moreover, if we learn some subjects more than others, we know it better, and it’s useful to enter to university
However, some students don’t know what they want to be, and it’s not bed for them to study all subject equally.
Probably, they could find something interesting in subjects that have never interested them before. And in modern world it’s very important to be comprehensive developed person.
Nevertheless, usually, students don’t understand all subjects equally well, and sometimes they consider themselves stupid.
Also, when all subject have similar umbers of hours , students don’t have enough time to understand them as well as it’s necessary.
All in all, I strongly believe that being free to choose what to study is an effective form of education. Nevertheless, I must admit that we should not completely reject all the other subjects. Instead, teachers must find an easier and more exciting form of teaching them.
