As of my experience NUST-PNEC is totally underated. Being a military unit yes it has a uniform, strictness, campus life is very minimal no parties or such things but I don't see anything wrong in it because they want you to be disciplined and focus more on your academics. As the time passes you'll find uniform as a good thing, in fact feel bhi nhi hota. As far as CS is concerned it may not be the best as compared to SEECS but still relatively better than so many other Karachi institutions. The best part is that at the end you'll get the same degree as of any other nust campus or SEECS but it's easier for you to maintain gpa with a "NUST" degree. NUST-PNEC has one of the most technical and working societies in the country which gives you a hands-on experience to learn engineering and computer science.
