Dear Karan, we are already in the first week of September as we talk. Assuming that all the rounds would be completed by September 7th, we also need to remember that Students are given a specific time to join the allotted colleges. So, it would be safe to be prepared to attebd classes from the 3rd week a little after the 15th. There is mandatory Orientation Class program that needs to be attended as well. So we can assume that it might start after the 15th.

Hello,
Well, it totally depends on when the seat filling procedures of government gets over. If it will be done on schedule date and time then you can expect that the colleges will start from midway of October or first week of november or if there will be delay in the seat filling due to any issue then the day of opening might also get delayed.Though it may start early too as there is no official date is announced.
I hope this helps.
