No. It is very difficult to get cse/IT  at 140 but you may get DSE or ECE.

Hello aspirant, first of of congratulations on getting a score of 140/240 in MET 2021. According to previous year trends you need to get at least under 2000 rank which is about 130 marks to get a seat in CSE in Manipal main campus. You can also opt for ECE branch at Manipal main campus.

Manipal main campus is much better than Jaipur campus in terms of placements and academics, specially because the main campus is much older. Manipal main campus also has better faculty and academic infrastructure. So students generally prefer Manipal main campus because Jaipur campus is relatively new and does not have a good placement record than main campus.
