For courses like Basic Para, don't get your hopes up and expect it. There is limited number of positions on the course that will be givin to the Brigades and you will be competing against others. You could get on that course, but you may not. With a lot of the courses that are run out of area, it really comes down to right place, right time, being in good standing with the unit, and being fit. Also, you don't need to be Infantry to get this course, it is open to all trades.
Basic Mountain Ops, if your unit runs it, very good chance you can get on the course. Otherwise you will have to wait if another unit in the area is running it and offers positions to the unit.
For right now, just focus on the short term, ie getting into the Reserves, then doing BMQ and DP1, everything after that is far away for you at this point.
