Before you choose your subjects, think about what you want to do in the future. Are you interested in science? Do you enjoy literature or languages? Have you always wanted to be a journalist? Does the thought of being an accountant give you the shivers?
Most high schools allow students to make their own subject choices.
If English isn't one of your favourite subjects, don't worry! It may surprise you to know that English isn't just about writing essays and novels. As well as studying literature, English classes also focus on language skills such as speaking and listening, which are valuable for everyday life. You will also need all these skills when you find a job or go to university.
The most important thing is to find the right balance between what you are interested in and what is likely to get you the grades you need. Don't worry if it takes time to find this balance. If one subject isn't working out, there is always the option of switching subjects in later semesters.
If you are really struggling with the decision, ask your teacher for advice and find out if there are any careers advisers at school who can help you.
