Nitish, it seems difficult for you to get admission CSE branch in Global Academy of Technology - [GAT] - Bangalore. This is based on your rank and previous year cutoffs. The branch closes at around 15,000 here. You can definitely get the other branches there. 

But again it depends on the number of students who appeared for the exam and as well as the difficulty of the paper.

Feel free to ask if you have any more queries.

Hope this helps!

All the best!
