Greetings of the day 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 78/240, its a bit hard to get the top branches like CSE, ECE or IT in their main campus, i.e. Manipal . You have chances of getting other branches like Industrial Production, Civil, etc. Whereas, you have high chances of getting seats like ECE, It or even CSE in Jaipur and Sikkim campuses. So, just apply to their counselling process and as it is conducted in different rounds, your chances of securing a seat increases.
