Howdy Eric,
If you wait until after the 30th of June, you probably won't get in. Unless a huge number of other candidates also decide they aren't ready and simply don't show up for appointments... but the way it works is that once 400 exams have been taken, then your voucher will be cancelled. So -- if you want to be in the beta, you probably need to schedule your appointment no later than the 14th (and I am not sure that even this date will be safe -- it could still close earlier). There is a good chance that waiting until the 20th will be safe, but no guarantee.
So, if you know you won't be ready before the 30th, then you probably shouldn't try to take it. Unless... you DO have time to do at least *some* studying and cramming, and you just go for it in the middle of June sometime, which means that at the very least you will get a chance to see what the exam is like, in preparation for taking it *for real* when it comes out in August.
My recommendation would be:
* If you already know
EJB AND
* you have at least a *little* time to devote to studying
THEN schedule an appointment for mid-June and take it.
Otherwise,
Wait for the real one, or as you said, keep prepping for the SCWCD exam. You can always take the EJB exam later. Be warned that the SCWCD exam will be updated, we think sometime in the fall, to be based on the new spec. There is probably no reason to wait for the new one, but I just want to make sure you're aware of that.
cheers,
Kathy
