A subject that I think should be replaced from school programmes. In general, there are only a few subject that I think should be removed from school education curriculum. But the first springs to mind is Abstract Algebra, which include solving quadratic equation, learning analytic geometry and linear vector space. I think there are many reasons why it is unnecessary for students to study Algebra at school. Firstly, it's such a waste of time to teach children how to solve quadratic equation because it's not an essential knowledge for them when they leave school. Secondly, the education program require students to remember too much formula and the instructions provided by teachers are not so easy to understand. Finally, my experience tell me that the analytic geometry lessons in Abstract Algebra is extremely difficult for children, especially for those who are not good with Maths and abstract thinking. Only professional mathematicians or computer scientist can study it because it's related to their field. If I could choose an another subject to replace it, I would suggest the school to teach martial arts such as karate or taekwondo because it brings the benefits for students to improve their health and to develop a strong immune system. Moreover, martial arts also teach children the martial spirit so they will be able to help other people and protect themselves in bad situations.
