Im sure there are text they give you there or something like that. But is there anything you wish you had have memorized (ie a list of acronyms) that would have made that first week a little easier.
You will receive a pre-course training package approx 1 month before the course start date, this package is in the process of being changed so I cant tell you what is included.
I would suggest that you actually read the pre-course material when you receive it unlike some trainees and you should be fine. There is nothing too complex in the first week or so.
The only other thing I would suggest is if you are not proficient with the phonetic alphabet you learn practice that.
