Hello Aspirant,

Chances are very low to get admission in both NG Ranga or SUV. Especially being from OC category , the required cutoffs rank should be below 200 at the least for top institutes. But there are other colleges you may try :

Madanapalle Institute of Technology and Science, Chittoor

Prasad V. Potluri Siddhartha Institute of Technology, Vijayawada

Rajeev Gandhi Memorial College of Engineering and Technology Nandyal, Kurnool

SRK Institute of Technology, Vijayawada
