Your teacher is likely to ask you to describe your school in the speaking test. You should learn answers to all the obvious questions: questions about your subjects, the school building itself, the teachers and your plans for after school.
You should realise that you may be tested on your tenses by questions about what you did yesterday at school and what you will do tomorrow. You may also be asked an opinion about your school.
