Yes yes, that's correct. You just can't rely on one reshuffling, that's why I'm saying wait for vmc results, because unlike fiitjee they tell batches as well along with your results.
As you mentioned you are getting 60% waiver, I think you will be in 4-5 batch in fiitjee.
I got 90% waiver, and I got 2 natch, but there were students with me who got 75% and 60%.
So I would suggest you to ask them, which batch will they be allotting you.
