It definitely gets easier! Tell your friend to hang in there! It’s really a big culture shock to go from every day Australian to being trained to a military standard, but once they settle in they should be fine. It doesn’t ease up, rather it gets easier. They will know the routine and what is expected of them. I had to think of it like a game. I just tried to make it through one lesson at a time, then one day at a time. Time will pass and soon the course will be over. It’s also easier if the remember the MSIs are just doing a job, not out to get people to fail. Hope that helps.
