The long running time of the school can explain the strength and quality of the school, rich experience in running the school, and provide better technology and employment platform for students.
Then, it depends on the learning environment of this school. This requires on-the-spot investigation, knowing more about some schools, and a good learning environment can promote students' better study.
Finally, the strength of running a school also needs to be considered. Try to choose big brand schools all over the country, so as to ensure that the teaching equipment you use is advanced.
