Hey,

No, There is no Fee concession even if you get good rank in AUEET. You will definitely get the course you desire in Andhra University if you score and get good rank in AUEET but the fee is same for every candidate whoever gets admission and qualifies the exam to take admissions in the university.

You can apply for fee concession though and for the details you have to visit the  official site and contact the authorities.

I hope this helps.

All the best!
