Has any of them lived or studied in Karachi? if that was the case there woldn’t be majority of non-Karachite student in these institutions. I suggest speak to non-Karachite graduates from Karachi and they will give a clear account of what goes around in these universities and colleges. Don’t base your opinion on what you hear from people, who never had any exposure to that environment. whatever you choose, NUST or Karachi UNi, you will be safe if you concentrate on your studies ONLY. :k:
