is kmec at ngit Uppal better college

If you mean KMEC (Kommuri Pratap Reddy Institute/associated campus) compared with NGIT, I would put it this way:

For placements/reputation:

NGIT > KMEC, based on current student discussions.

Recent student feedback has commonly placed the order approximately as:

KMIT → NGIT → KMEC

for placement strength. Students also report that NGIT and KMEC share the same campus environment and some academic/coding resources, but KMEC is generally considered a step below NGIT in placement reputation.

My recommendation

If your options are:

NGIT CSE vs KMEC CSE → choose NGIT CSE.

If the choice is:

KMEC CSE vs another college with a substantially better placement record → compare the other college first.

KMEC can still be reasonable if your priority is getting a CSE/CS-related seat and you are prepared to build your coding skills independently. Recent students have specifically described the college as more suitable for someone focused on academics/placements than someone looking for a strong campus-life experience.

Overall:

KMIT > NGIT > KMEC for the three, based on the available student feedback.

But your branch and your actual alternatives matter a lot more than the KMEC name alone.
