Heya!
Going by the last year trends, cutoff for CSE after spot round was around 114 marks which means rank of 41k and this year 41k rank is having 95.5 percentile.
While for the CCE it was around 96 marks having rank about 62k and this year 62k around 93.4 percentile.
This year, taking care of increasing average packages and growing popularity of LNMIIT, you should have 96(for CSE) and 94.5(for CCE) to be on safe side.
Hope it helps.
Thank You
