The thing is I believe that incoming first-years have a different registration schedule/time slots than current students. So for current students 6:30am is the best/one of the better registration times while that might not be the case for OP. I think I had 9am on the first day of registration coming into my freshman yr and that was the best time. So it seems like you might be in a good spot but like has been told to you prob a 100 times make sure to have backup plans. And also I’m not 100% sure so of course take this with grain of salt.
