Dear, there are sadly no institutes like King's College, Oxford or Cambridge in Pakistan. The level of learning and exposure you get from these institution arm you with a plutonic method of critical thinking. something none of our universities can offer. Its sad but true. The important thing is go to learn, and come back with a pledge to serve your country by utilizing your expertise, despite the hurdles that you will face in doing so. Don't loose your identity, strengthen it instead.
Surely you have heard of this hadees: Gain knowledge, even if you have to go to China for the achievement of this purpose.
