hello,

 cutoff for KMC Manipal in 2018: 494 marks was the cutoff in the first round, and it went up to 506 marks in round 2 and went up further to 521 marks during the mock up round.

So, according to the cutoff , your relative has a very good score and has good chances for getting admission in the college .
