The fact that you want to join FFC is very ridiculous to be honest. No doubt FFC is one of the best organizations out there but why do you want to limit your intellect to FFC? There is a whole world out there....you deserve far more.
At this age you should choose a field of study that interests you, rather than a job. (you are narrowing ur focus a little too much, in near future you will discover more disciplines within a field that click you, and may be they are of no interest to FFC, dont get stuck at a point)
I dont think UET is a good option, went for a training there for 2 weeks, the environment is too bad as per where the world is going, I think it even lacks average Pakistani university standards now a days.
GIKI is good option, but you have to be living in Topi which is not too comfortable for me, you make your decision. (plus do put cost of studying in ur calculation, people are studying medicine for private universities to become doctors, whooping easily over 3 million rupees, not good! not worth it at all!)
LUMS is believe has excellent faculty and environment Believe me environment would matter a lot more than just courses. Every university ALMOST offers same courses, its how you teach them, the dynamics around that simple course. A professor from LUMS taught me a course partially (graph theory), im sure most of the people would be unaware of the excellent method that professor used to teach us. I use it today to put thought into others head now. Thats what matters at the end of the day how you perceived education when it was being provided to you. (expensive place to study though)
NUST is a good option. If you come to H12 campus for electrical engineering you would find excellent faculty very motivated and learned. Not much Phds at MCS campus and fauji mahol is there, no fauji mahol at H12. (dont go for environmental, civil engineering at H12 campus, terrible faculty, graduates are hired to teach, not even masters).
Now I will be honest with you, even if you study at a 3rd class institute, what matters is what you perceived and learned from what was delivered to you and you found in books. How creative you could get and what kind of skills you could develop. Any one can become an engineer, its not that hard. Identify your unique capabilities A product gets success in market only if it has some unique selling proportion to it. If it is 'just another product' it would live an unimportant/undefined life. Make an excellent product out of yourself, where ever you get a chance to study at.
