Starting off first, let me congratulate you as you have attempted the Amrita University Entrance exam.

Coming to your rank, let me assure you that 12000 is not a bad rank at all. Many students who have scored a rank of 20000 to 30000 also have qualified for admission at Amrita University.

There are other additional factors that also come into play. Your admission depends upon which state you are from as well. This could be Telangana, Andhra Pradesh, Tamil Nadu or Kerala.

The college has certain cutoffs that have been set for each state. You can also get in touch with the college for information on this but they might ask you to pay up.

However, if you are considering enrolling here for CSE, most of these seats get filled up at 6000 rankings, even in-state quota sometimes. So for 12000, you can consider going for branches like Chemical Engineering, Civil Engineering, E&I as well as Aero. These are definitely available under the state quota.
