Not very helpful, Basic Up makes the three weeks in the field look like a pleasant camping trip. Wasn't quite the case. Basic Up fails to talk about the first four weeks which are death by powerpoint, also they don't mention things like how long you are CB (confined to barracks) for. Little things like that, that might have been nice to know before hand. There are a few other example but I won't go into it. The only thing watching those videos did for
me was the ability to say "hey there's that PO from Basic Up"
Not to mention, every course is different depending on your staff. Anyways, this is just my opinion...your experience at St-Jean could very well be similar to the series, I'm sure you're looking forward to finding out yes?
Cheers, Kyle
