What if we didn't get college in second cap round? Can still we get first cap round allotment college?
No, you cannot get the same college allotted to you in the first cap round if you don't get a seat in the second cap round. Once you accept a seat in the first round, it's usually considered confirmed. If you didn't join the college after the first round, the seat is likely released for other candidates. By the time the second cap round comes around, the seats in your preferred college might already be filled.
I hope this information helps you.
