School admission process

Hey Guys! Making sure I am doing this school admission process right, we are moving from overseas so I never took admission in Kerala schools before.. we're supposed to contact the admissions officers from 3-4 schools we're interested in > give previous year mark sheets etc > assuming 2 schools short list the student for admission > confirm and pay fee for one school > then we tell the other school(s) that we took admission elsewhere? Is that how everyone does it? Thanks!
