Hi,
Shqamar, i shared my life experience so as it may make your choice for your kids simpler. You are welcome.
Everyone in Pakistan is concerned about educating their kids and above all if you want your sons/daughters to excel in life, they must get proper schooling and perhaps go abroad, on scholarships/funding. That is the ultimate dream of any parent.
Regarding your queries about montessori, well i never went to any. I started my grade 1 in 1995 and completed A-levels in 2008. All i want you to know is that what ever school you send your kids to, make them switch later on. Maybe St Patricks, Beaconhouse, Karachi Grammar or Habib Public. But also make sure that you raise your kids properly, teach them all the languages with as much passion as you would want them to learn English.
I hail from Punjab so Punjabi, Urdu and English, make me tri-lingual....a big big advantage over so many others when you are living abroad.
Good luck and happy parenting!
