Hello Karthik!
If your rank is quite good then trust me, there won't be difference. My friend literally got the same seat from mock allotment 2 to 7th round. However, there is no harm in waiting. what if you get something better? the counseling can be really unpredicatble at times.
Hello..!!
Each and every round is important for JOSSA counseling. Seventh round stands separately because it is the last round. There are few interesting things about this round. One, your seat will get freezed automatically and you don't need to report to any IIT, you just need to go for the alloted IIT for verification and admission. And secondly it is good to leave it till seventh round if you don't get preferred seat in between.
Hope this is helpful.
