First of all Congratulating you on your nice performance that you deserve such a nice college and I would like to tell you that knit sultanpur is among top college under upsee and above all it is a government college. So if you were to take my opinion then I would suggest you to take admissions in this college.
Good luck for your future :)
Feel free to ask if you have any further queries.
Overall KNIT is a decent college. As it's a government college under AKTU it's fees is quite low. When it comes to Civil I have lesser idea on how the placements are in core branches but overall curriculum wise KNIT is under AKTU and it's syllabus is not updated at all. The same is going on. But currently they have been working hard so you could expect a good result.
Best of luck
