Switching to a health care class is a case of curriculum adjustment. Generally speaking, it is necessary to communicate with the PE teacher and get permission. There may be differences in the teaching contents and requirements between physical education class and the health class, so it is necessary to negotiate with the PE teacher to ensure that the transfer formalities can be successfully completed and get the consent of the PE teacher. The specific transfer regulations may vary from school to school and from region to region. I suggest you consult the relevant regulations of the school to ensure that you can transfer classes according to the requirements and procedures of the school.
