According to my point of view,

It completely depends on the branch you select. Some private colleges are very good in particular branches like CSE,ECE than government universities. So it depends on the branch you opt for.

But here are some good colleges in AP based on your rank,

Godavari institute of Engineering and technology, Aditya engineering college, KL University, Vignan university, Sree Vishnu educational institutions, Raghu Engineering College , Anits ,Mvgr.

The above mentioned colleges gives you knowledge and adds value to your certificates.

But If it comes to placements in particular branches like CSE and ECE, Vignan and Raghu engineering colleges are showing best results in bringing top product based companies with good packages.

Not only the rankings but also take reviews from the students studying in the college before you choose anyone.

All The Best.
