Hello Sreerekha !

You didn't mention any category, so I considered you belong to the general category(non-minority). I also considered you to be a keralite.

With all these above assumptions, your chances to get any kind of branch through CUSAT is really tough for a rank of about 9000+. The closing rank for almost all kind of branches is below 6500.

You can check using the link below in case you belong to minority or have any other reservation.

All the best !
