Hello harshitha,

For 18,000 rank in apicet,  it is very difficult to get a seat in Jntu kakinada. Your category also plays an important role in determining the college, so if you belong to open category then there are no chances for getting jntu kakinada. If you belong to reserved category like sc or st then you have lower chances of getting a seat in jntuk.

For your rank the possible colleges are as follows

Madanapalle institute of technology and Science

Prasad v potluri Siddhartha institute of technology

Vasi reddy venkatadri institute of technology

Sri vishnu engineering college for womens

Hope this helps

Good luck
