Find a LINK is FFC best and simple way, other thing is there is No sure way how you would get in there. Plus there are many more employers who give same or better package.
I dont know what type of a person you are but as per me UET is more of the FSC and nerdy place there is no life there, guy with o/a level background will get fedup.
Furthermore IF you are going for engineering or being a doctor its really not your choice
All depends on entry test and where they put you in.
Give entry tests of UET, GIKI, Lums, Nust
which ever gives you admission in Electrical or mechanical will be the best.
UET= No life(50,000 yearly fee i think
GIKI= awesome place(best as per me) 300,000 + eating and stuff
Lums= Good but dont know details of their faculty members and stuff. 300,000 though i am not sure
Nust= good one but you will have to do bit of army thingys, obey timing stuff blah blah fee is less then others but more then uet i guess
