Greetings dear Sreekanth

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 140/240, its really hard to get CSE or IT branch in their main campus, i.e. Manipal as there is a huge competition for these seats. The cut-off of CSE branch at Manipal campus was 781 in the year 2020. So, you can try for CSE and IT branches their Jaipur and Sikkim campuses. Just apply to their counselling process and as it is conducted in different rounds, your chances of securing a seat increases.
