Hello Aspirant,

It is difficult to say exactly which all colleges have more number of GATE takers, but it can be considered obvious that top engineering colleges would be having many GATE takers. Recently students of National Institute of Technology, Warangal (NIT-W), secured top ranks in the exam.

Jawaharlal Nehru Technological University College of Engineering, Kakinada

Koneru Lakshmaiah Education Foundation, Guntur

Andhra University College of Engineering, Visakhapatnam

Vignan's Foundation for Science Technology and Research, Guntur

These are some top level engineering colleges in AP with probably many GATE aspirants.
