I am pretty sure that no one on this board knows the dates of future classes or if a certain class has been filled.
In the rare event that they do know, I don't think they would be at liberty to tell.
In other words, we find out when they put the class picture on the website.
If you have been interviewed, you will find out when you get the phone call or email or whatever they do these days.
Until then, you will just have to be patient.
