Greetings dear aspirant

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 131/240, its not possible to get CSE or CSE with any specialization 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. You can try applying for other branches in Manipal campus like Mechanical, Biotechnology, etc. Also, you can try for branches like CSE, IT, ECE, etc in 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.
