Hi Swaroop,the admission into the colleges JNTUK Kakinada and JNTUK Vizianagaram will be based on the merit list which will be decided on your performance in AP ECET 2019.

According to the marks you have mentioned,your rank may lie between 12,000 to 25,000.

Your chances of getting a seat in Jntu kakinada or vizianagaram is seemed to be slightly impossible.As the closing rank for those colleges is below 10,000.You can still get a seat if these ranks come down.So,don't panic and you can apply for even other colleges like :

Lakireddy Bali Reddy College of Engineering, Mylavaram ,

RVR and JC colleges of engineering,Guntur , 

Bapatla Engineering college and

Sri Venteshwara college of engineering

and many more.
