You have to make your own plan. You can sign up for a badminton training class. It is estimated that it is difficult for you to practice both at the same time, mainly because of insufficient energy. Do you still have to do your homework? Make a plan for yourself. Besides studying and exercising, you should also learn to do some housework, such as cooking according to recipes and cleaning windows. Don't work only when you are on duty at school, but also at home. A good plan is difficult to implement. I wish you a happy summer vacation!
