Boys and girls, welcome to Elite Secondary School! I’m Mr. Green, in charge of this school. I’d like to introduce you to various aspect of our school, from our history to our buildings and activities. Elite Secondary School set up in 1960. In the past fifty years, Elite had experienced a lot of changes and developments. Our school finally decided to move to Aberdeen in 1990, due to the lack of the space. The school campus now was almost three times larger than the previous one. We even have three libraries which are available with all the teachers and students. As for laboratories, they have two Physics labs, two Chemistry labs, and a Biology lab which was established last year. Students here always have an enjoyable time at school because there is a widely range of extra-curricular activities for them to choose. We try to provide as much activities for our students as possible. Elite Secondary School is committed to providing the highest level of education to the children. Thank you for your time.
