There should be no compulsory school subjects

Every day thousands of students are visiting a secondary school, where they are learning definite subjects, like math, physic, chemistry, history, official language, other languages, sport and other. Unfortunately, one part of students are complaining about subjects, which they hate, or in witch they have bad success. Sure, wherefore they don’t want to learn them. On my opinion it’s absurd, that in secondary school students must learn all these subjects, therefore, that secondary school isn’t obligatory.
From the one hand, it’s good, that student learns something about various fields. It may help in all of person life, for example – languages – for right pronouncing, orthography and so on so on. Moreover, it educate people’s mind. Certainly students, who are learning all subjects, are more intelligent.
