Hi Chrissy,
Yes if you didn't work on it, it would definitely be deleted by now. We have a limited number of student environments so when people finish or if they aren't being used. Are you ok with waiting until @Jesse Sharp returns? He'll be back on August 20th. I've already sent him a note and a link to this discussion so he knows to set you up right away.
Sorry, I expected to get some R12 ETBMA exam requests while he was gone, but we haven't really had a lot of R11 requests lately so we thought we'd be ok. The process is a bit different and I don't have all the details.
