hello aspirant,

see every year cutoff varies, and it depends on number of candidates, questions difficulty level, seat matrix etc. somit is not possible what will be the cutoff for self financing colleges , however several marks more than cutoff will be good, 300+ is a safer side

you may use career 360 college predictor to know your probable colleges,
