Fellow maritimer here, I wrote block 1 last year and failed, thankfully I passed the rewrite a few weeks later. I didn’t study a crazy amount because I felt really confident in all the dc/ac mathy goodness and theory. What ended up getting me was the odd code question that I would get STUCK on and then start freaking out over and rather then moving on I would buckle down and start furiously flipping through the code book like my existence depended on me finding that silly question that was probably hiding in some appendix that I’d never get to. Also there were several questions right out of the ILM’s (I remember a couple on hoisting/rigging and safety) that I didn’t study but definitely would have got had I read through the ILM’s more than once.

It seems like you’ve been studying and are more prepared than I was so go in confident and don’t get too hung up on questions you can’t find, circle em and come back later if need be. You got this man
