Well, I can tell you that, in the rigid structure and highly competitive nature of the Korean school system, also known as pressure cooker, not everyone can do well in that environment.
Saya boleh beritahu anda, sistem persekolahan di Korea bersifat tegar dan  mempunyai persaingan sengit, ia disifatkan sebagai "periuk tekanan", bukannya semua orang akan berjaya dalam persekitaran itu.
