Greetings dear apirant

Firstly, congrats on successful completion of your MET exam. 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 180/240, its quite possible to get CSE branch in their main campus, i.e. Manipal. The cut-off of CSE branch at Manipal campus was 781 in the year 2020. Just apply to their counselling process and as it is conducted in different rounds, your chances of securing a seat increases.
