Dear Parents,

First thing you need to clear that whether your son is belong from Tamil Nadu or not.

If your Home town is in Tamil Nadu then there is no need to worry about the marks, in the score of 137 your son rank should be around 3k, and you will easily get CSE in main campus, you just need to take part in counselling and they will alot you in very first round.

But if you are from state other than Tamil Nadu then there is less chance that you will get CSE or any specialization In CSE but there is a huge chance that you will get CCE here, this branch is similar to CSE. Try and definitely you will get in further round in counselling.

Best Of Luck!!!
