I wouldn't stress about it - I think they have their meetings a couple of times a week.
I did mine in december - a couple of friends did theirs mon and tues and both got an email on the weds. I did mine weds and nobody from our day got an email till the following monday, so I wouldn't read anything into it.
I've got my sim coming up, and yes, the month or so wait is definately worth it to do as much prep, revision etc as you can. I am having considerable success in practicing with MS flight sim 2004 with the pmdg 747-400 add on - it has a working FMC and good cockpit screen displays. Very useful for getting the scan going and working out how the FMC tunes the navaids.
