Написать эссе "High school students should study only the subjects they choose"

Nowadays, pupils in high school have a lot of different disciplines. Some people claim that students should learn only the sciences they want to learn, while others think that schoolchildren should learn all the subjects. I am utterly convinced that high school students should study only the disciplines they are interested in. Firstly, teenagers choose subjects that will be useful for them in their future work, so learning certain sciences helps to get deep knowledge in their occupation and not to be distracted for useless disciplines. Secondly, pupils choose the subjects that are interesting for them, so students will like to go to school and to study, because it is not as boring as it was when children should study lots of disciplines.
