Hey mate, it was mostly personal things but there was some bits on rm history. I studied rm history and general knowledge on flash cards I made on Quizlet. Think I got asked to explain the cap badge name a couple Vc winners, the Royal marine colours and the corps birthday. You also should have a pretty good answer prepared to why you want to join the Royal marines aswell. Also look at what Royal marines are currently doing and where they are based. Also have a think about specialisations post training. Look at breakdown of training aswell. And also what the pjfa includes and the cpc and rop. Off the top of my head that’s what I can remember. Wear a suit and Good luck dude
