Good attitude Torlyn!
As for the Support Staff, the experience of myself and many others is that they were very rude. But we found that it had nothing to do with language...they were equally rude to everyone (can't accuse them of prejudices). I don't wish to comment on their capabilities there, as it may be the "one bad apple" syndrome, other than to say that, before I left for course, my RMS clerk did everything for me here (plane tickets and claims for return trip - even though the message said St Jean would take care of returns) because she said, "They do nothing for you there and they're impossible to deal with!" Hey...it's what a fellow RMS Clerk said about her peers, I'm just relaying the message.
Regardless of someone's opinion, to get back on topic, if you don't have French Language Training, you shall take it at the Language School in St. Jean, immediately after your BOTP. The only time I know that the SLT can be taken elsewhere, is if you are an Officer that has been Commissioned from the ranks.
Whats the teaching/course structure and language standards there like?
There is some excellent instruction available, and you are treated better than a recruit. The course structure does change, so I wouldn't want to comment too much on that. The language standards are the same as the Civilian equivalent (ie: A, B, C, & E - A being the lowest). That being said, I know of some people that come out of St. Jean knowing little more than when they went in. This had nothing to do with the instructors or course content, and everything to do with Attitude. If you finish course with three A's, so be it. But the goal is for three B's (Reading, Writing, Oral Interaction). As with University, they can't make you learn, they can only provide you with the materials to do so. It's up to you as to how proficient you wish to become in this new (and highly valuable) skill.
Hope this helps answer most questions.
Chimo!
