Hello!

So according to your rank that is 16,000 your chances of getting CSE SRM Kattankulathur are very less because the cutt offs for this branch usually closes at 8,000 and yours is far above that. This is the main campus so seats are less.

You can try in another campuss like Ramapuram or Vadapalani where cutt offs usually closed around 12000-14000. Attend the counselling you can get a seat in later rounds.
