I have choosen no.4 - very regret & thinking of switching to another one.
Have been to no.6 - no good - even don't want to pay the registraton fee - no need interview.
Have studied in no.7 - highly recommended - principal and teacher is so caring and nice with dedicated heart. every one in the school knows every student. but no NET teacher.
In terms of reputation - no.3 is having long history and good reputation. but school campus very old. have high academic standard.
