based on the threads i read here:
1) YMT - often praised by media. with good principal and teachers, and facilities. many graduates went to good secondary schools.
2) CSK LS - tied to 2nd tier secondary school
3) KLT Govt - BillyM always says that its students are just so-so in terms of everything.
It is unnecessary to have such ranking. The most important things are on the child's ability and input of the parents and teachers. What do you want your child to be? What is the ability of the child? Does he cope with a lot of homework or very hard subjects? Do the parents spend a lot of time in teaching the son? Don't just rely on the teachers of the well known school. In fact, they cannot help. Don't just focus on the name of the school.
