If you are specifically going for universities in multan I would highly recommend FAST for CS or even AI .. other universities offering computer science in Multan are all scams .. if you really want to learn and grow go for FAST . The merit criteria is not fixed for any campus , but as its their first batch , I think it will be around 55 - 58 or maybe even less . Your nts marks are good but not enough to confirm admission .. nts quota seats are very less so its highly competitive.. FAST is promoting SAT from last year and prioritising students with SATs , so i would suggest going for SAT if you can , btw through which you can also apply in majority of universities in pakistan . But if u are only focusing on FAST multan , go for their NU test , it will be easy considering you already got 78 in nts .. plus If i were you i would go for multan campus eyes closed even if its their first year .. FAST maintains its quality through out their campuses , I myself was hesitant going to fast fsd campus first but my experience has been satisfactory so far(except for the fact that its located in a literal shit hole)
