IELTS WRITING TASK 2: Some children find some school subjects difficult (for example maths or philosophy), so these subjects should be optional rather than compulsory. To what extent do you agree or disagree?

There are a lot of subjects at school, some of which are relatively hard to study. Therefore, several children want those subjects to be selective.and I totally disagree with that opinion for the reasons I'll explain later in my essay.
Firstly, it's quite true that Maths, Chemistry or Philosophy are very complicated and can be daunting as well. They require a clear and accurate understanding of every detail or formula as well as a great deal of intelligence and patience. Whereas not all students are good enough to study subjects like that, some are even scared of them. So evidently, they wish such subjects to be optional instead of compulsory as usual.

However, despite being very difficult, the subjects are immensely important for young peolple to do anything in their daily life. What is more, significant gaps in basic knowledge can result in some serious consequences. For example, if you don't spend time learning Maths, you won't be able to pay your bill or check your salary exactly.

Second, if we make these subjects selective then students only have to study what they like and find easy for them. Gradually, they might lose the ability to confront and overcome difficulties in study and life because they don't need to persevere in complicated subjects. Moreover, they might not have the chance to experience feelings of pressure or stress when they strive to do something that is really hard for them. And that lack of the most important survival skill can lead to a lot of failure in their life after finishing school.

Another reason is that Maths or Philosophy can help students develop their logical thoughts and the ability to see kind of beyond things. Thanks to that, they can have more great opportunities in their career.

In conclusion, students should try to study all subjects even the difficult ones at school because those will be very helpful for students when they move into the world.
