Exams in CHS are hard compared to other schools so it made you work hard more, and feel that gov exams aren't that hard haha
well i believe it's not easy to enter now. during my time (5years ago) it was still considered easy to enter as long as you got good results. nowadays students with straight A in UPSR can't even get in.
