Hey, I was a Communications and IT Specialist. I joined as a Able Rating, rather than an officer.
The basic training is pretty hard, but then I was only just 18 so it was a bit of a culture shock! The fitness is the hardest part as you have to keep up with the lads, especially during the assault courses and obstacle courses which are killers! Lol. And having to jump off a really high diving board wearing overalls when you are scared of heights is pretty scary! Lol.
You'll be joining as a nurse I assume? They are very well respected in the Navy and you get a really cool uniform and you don't really go to sea, which is a good thing, but I think you still go to places like Afghanistan, as they'll obviously need you there.
I loved it in the beginning so good luck to you, I'm sure you'll have a very successful career!!
P.s. If you do go away, the girls will be queuing up for beauty treatments too! Lol. Everyone used to come to me at sea for brow tidies, etc, even before I was qualified! Xx
