I took it. I am an out of rate MK3 and i thought alot of the questions were pretty crazy. But I dont have sea time so not having alot of daily maintenance experience on cutters really hurt me.
Good so at least I'm not the only that felt that way. I've been attempting to remeber questions and figuring out what references were used to generate them specially the electric wiring code type questions.
Don't be too discouraged. It's rare that someone comes out of a SWE and is like "wow, that was easy" I have come out of all mine thinking that I did so poorly that instead of getting promoted, I would actually get demoted. I placed in the top 15% for all of my SWEs too. I seems that if you've always been on cutters, they ask station type questions and if you've been at stations they always seem to ask cutter stuff. Don't sweat it, the rankings will be out in 6 weeks or so.
