Well although it is a separate issue. I will reply to this. First of all, please be sure that NUST does not announces any score of the entry test. They announce only merit position. 15000 students participated in the competition test. My merit position was 1209. I was offered PNEC Mechanical Engg in the second list. In the first list I was not selected. I talked to nust HEADQUATERS in H-12 Islamabad. They told me that I can get Chemical Engineering or Civil Engg OR Computer engg at NUST Islamabad or Rawalpindi Campuses. The merits of Electrical or Mechanical engg are as high as 500-600 at Islamabad.** To my great surprise, I was even upgraded to ELECTRICAL at Karachi in third list. **
**Now i had finally planned to go to Karachi because there I have got the best disciplines. I can stay at Islamabad by joining low discplines like CIVIL OR CHEMICAL. So, I was all happy to go to Karachi. I had very good opinion of Karachi. But when I broke this news to my friends and relatives they asked me if I was a mental case. **Then everyone whom I consulted rejected my opinion.
So, I decided to put this matter to Karachites.
Well , its totally upon you and your choice.But if I have given the choice , i will prefer Chemical/Computer in my own city over Elect/Mech in another city rather another province.Its not only security issues , MQM Punjabi Pakhtoon thing , there are may other things which count.The comfort and relaxation that one find in his/her own house and city cannot be substituted for another city specially if you have spent your 12 long years of academia in the same city coming back your own house at 2 or 3 pm daily.Its a total change in lifestyle and ease and other benifits in one's own house. After a month or so returning from Karachi to Rawalpindi , sharing rooms and all other things are also to be considered.Last but not the least, Elect is saturated these days. Every private university is conducting Tele/Elect courses and market is full of it whether in cellular companies or other but Chemical is rare and job opportunities are great not only in Pakistan but abroad also in Gulf etc.For higher studies Chemical field is also diverged into various co-related fields.I know some people who are earning very smart at ICI , Dawood Hercules and other few other renowned names.
But in last , its totally upon you and your choice.
