Hello Ramana,

You have pretty good chances to get free seat in a college. The chances of getting in a college depends on our rank and the colleges chosen at the time of selecting options before seat allotment. So everything must be done carefully.

Coming to your rank,the colleges in which you might get a seat are : 

• Madanapalle Institute of Technology and Science - EEE(Fees-3.72lakhs/4yrs)
• Sri Sivani College of Engineering - ME(2.01lakhs/4yrs)
• RVR and JC College of Engineering - Chemical Engineering(4.32lakhs/4yrs)

• Loyola Institute of Technology and Management - CSE(2.05 lakhs/4yrs)
• Chebrolu Engineering College - ECE(Fees - 1.49lakhs/4yrs)

You can get a free seat in many other colleges but I have listed the colleges which I found good in rankings compared to others in your rank range.
