Hey Nandhana

Since you have not told me your category  I will assume you to be from general category.

According to previous year rank wise cutoff the last rank to get CSE in Chennai campus was 10,000. The last rank to get CSE in Ramapuram camous was 65,000 though. Most probably you will miss out on the Chennai campus but will easily make it to the Ramapuram campus by the 3rd round of counselling.
