Hello Jitendra some reputed colleges demand only appear for CAT but I Suggest you that dont stop after CAT give MAT entrance exam or else select some college where you want to take an admission and go for it see there cutoff , entrance exam , admission processor All the best Chandrashekhar

you score is too low you can give entrance test for any particular university or you can direct apply for any deemed university or college
