The best advice I could give you, as a prior student that was Dinq in off-crew and ended up qualifying first on my crew, is that you don't want to be that guy that sits in the TA all day. Those guys were perpetually dinq, or close to it.
Here's what I did. Systems not withstanding.
I bought a notebook, and went through and gave every casualty a different page. on the page, I would write the immediate actions, a brief synopsis of the follow up actions, in common sense form. And then I'd read over the WHY side of the page, then close the CP's and write off in teh margins the WHY. I would also write off in the margins any other casualties that were initiated or that my actions initiated. At the bottom of the page, I had a short two or three word list of everything that each watchstation should be doing.
I spent probably three days doing this for every casualty on my qual card, and then I took my qual card and that binder with me everywhere I went. I spent virtually all my time on the boat either studying, or talking to instructors to see what amplifying information they could supply me, getting checkouts or watching other students perform casualties. The next time I sat in the TA, I was studying for board.
If you're not in a check out, you should be waiting for a checkout. if you're waiting for a checkout, you should be studying as well.
It seemed to me that the students who went about the prototype experience with a notebook of some form faired better than those who didn't. I thought it helped because when I did it that way, I only had to translate from the technical writing to common english once, vice every time I needed to look at the information. (the last 10 pages also had every specification for the various systems, because lets face it. you have no choice but to memorize the specs.)
