After your initial trades training it is up to you.
Your training sequence looks something like this:
BMQ - 26 days (ish) Full Time or Part Time
BMQ - L 14 days (ish) Full Time or Part Time
Dp 1.0 - 60 days - Full Time only
Dp 2.0 - 1 week (online) - this course is a waste of time and you won't actually learn anything.
PLQ - 2 months ish - Full Time only (This course is required for MCpl)
Optional course(s)
Driver Wheel - LSVW/MilCot - 30 Days
MSVS and Air Brakes - 15 Days ish.
There isn't really much out there for actual courses after your initial training (BMQ, DVR WHL, BMQ - L, DP 1.0) , but if you want work in the summer there is the possibility to support exercises, or the reserve summer training cycle. You also don't have to work for the army the summers after that. I'd recommenced to get your BMQ, BMQ-L and DP 1.0 done as quickly as possible.
Your initial training likely won't all be in 1 shot either. You might do Basic on weekends , and then do Driver Wheel and SQ in the summer prior to your DP 1. It really depends on your unit and when you swear in.
Good luck, it is a pretty decent trade.
