Amrita Vishwa Vidyapeetham

There is no comparison between Amrita and CGC Landran. Amrita is a multi-disciplinary, research-intensive, private university, educating a vibrant student population of over 20,000 by 1700+ strong faculty. Amrita offers more than 200 UG, PG, and Ph.D. programs in Engineering, Management, Medical & Life Sciences, Arts & Humanities, and Social Sciences. Amrita Vishwa Vidyapeetham has emerged as the fourth best university in the National Institutional Ranking Framework (NIRF) Ranking 2020 for Indian Universities. Amrita has been adjudged as one of the "Top 10 Universities in India" for the fourth consecutive year. So Amrita is the best.

Most probably yes. Your JEE Main percentile is very good enough for getting Amrita Vishwa Vidyapeetham for B.Tech CSE.

Since you have a back paper in all these mentioned subjects, you might have some difficulty in understanding the basic concepts. So my sincere advice to you is to brush up all the basic concepts of accountancy, economic business studies and mathematics first. Follow your class notes properly or else ask some notes from good students in your class. After thorough revision of basic concepts, practice some sample papers for better understanding and to have a glance of different types of possible questions. Be motivated and confident. Hope this will help.
