Going as an international student on a B1 visa

[sheonki]

I was admitted in one of the US universities and I already have my B1 visa.

My F1 visa interview was scheduled for today but something happened and I now need to reschedule another one. I am worried I will not be able to finish the process before my travel date which is 5th of August.

Anyone was in a similar position? Is it possible to travel first on my B1 visa and figure out my F1 visa there?
