Greetings dear aspirant

Firstly, congrats on successful completion of your KLEEE Examination with flying colors. The cut-off trends keeps changing every year and it depends on the number of students attempting the exam, difficulty level, number of available seats, etc. With a rank close to 3000, you can very easily secure a CSE Seat in Koneru Lakshmaiah University's Vijayawada as well as Hyderabad campus as the cutoff for CSE branch at Vijayawada campus was 125 - 135 marks in the year 2017.
