You can go to Migao. Look at the national private high school library. You can look at the school tuition, admission conditions, teacher-student ratio, international student ratio, curriculum (AP course, honor course, ESL course, extracurricular activities), SAT average score, college entrance, itinerary, life and study. You can communicate with other parents and classmates in the group below the website. I hope it helps you.
Or go to the Apple Store to install a high-school library, which is also convenient to check.
