not sure about this but one reason for Ukraine (which is ridiculous to begin with) might just be that its a backdoor to sneak into europe, legally or illegally.
at the moment theres only a couple of Unies that are good quality enough in Pakistan. Especially for graduate courses, which usually require a decent research wing, which in turn requires government/non government funding. Pakistan just doesnt have that yet, and it would be prohibitively expensive to set something good up.
Exactly, and also the 2-3 top universities have a very tough selection criteria in the form of a screening exam. For instance, I remember there were over 35K (back in 2000) applicants to NUST (one of the best engineering schools in the country), and they had a class of 50 for each the 4-5 diff engineering majors, and same was the case for GIKi. Alot of people, both good and struggling students who didnt make it, went abroad.
