Hi aspirant,

This inconvenience is reported by many other candidates. Actually there are only around 260 seats available in each course to be filled through AEEE as a major portion of seats is filled through Jee main scores and some are reserved under management quota. Adding to it there are lots of rank where multiple candidates are tied up, that means there could even be 1000+ students in top 500 rank.

Talking about the probability of getting the mentioned courses in further rounds, it seems bleak as very few seats are expected to be vacant as most of the candidates above you would have received their preferred branches.

Hope it helps!!
