Hello aspirant.

First of all, congratulation for your great result in aeee 2020. 992 rank is pretty good. So, you can easily get CSE in amritapuri even without state quota.

But, when the scholarship is considered, it  is given to around 300 students.

Tuition fee waiver(scholarship) ranging from 90% to 25 % is awarded to the students, based on their rank at the time of admission counselling. Scholarship seats are earmarked in each branch in each campus. A total of 300+ candidates are eligible for scholarship at the time of admission and continuation of scholarship in subsequent years would require meeting the minimum required CGPA during subsequent years of study.

So, as per your rank it is little hard to get scholarship. But you can try for it as many rank holders in aeee do not join amrita.

All the best.
