Audisankara College of Engineering & Technology
Kakinada Institute of Technology & Science
Swarnandhra College of Engineering & Technology
Sir Vishveshwaraiah Institute of Science & Technology

These are just predictions based on previous years data. The cutoff varies every year depending on number of factors such as:
Total number of applicants
Total participants who sat for the exam
difficulty of the exam that varies every year and many more. So, these are not the actual results, these are just predictions based on previous year data.
