Hello student. 3618 is a good rank. But computer science branch is a bit competitive branch. That too when it comes to coimbatore campus, this is highly competitive. So there are lesser chances for you to get cse in coimbatore campus.

You can get other branches like civil engineering, chemical engineering etc here.

When it comes to amritapuri that is kerala campus. Yes, there are chances. Since there is a reservation of obc category , there are chances for you get computer science over there. But we might not be sure about it as every year cut off differs with various factors such as number of students writing the tests number of students attending the counselling etc.

So attend for counselling because chances are there. there are many other good colleges top which you can apply too

1. Ssn college

2, sastra deemed to be a university

3. Psg college in coimbatore

4. Vit in chennai
