Right, BP, these questions are answered in basic skills and reinforced in the training record book all 4th Class candidates are required to complete to meet STCW standards. I would expect a 1st year Cadet to be able to answer most, if not all of these questions. If you can't answer them now, don't attempt the 4th Class until you can, it's all pretty basic stuff. As a Marine Engineer of some 40-odd years experience, my advice is to get your hands dirty! "Booksmart" engineers are about as much use as a screen door on a submarine and should be banned from any ship, they're dangerous.
Keep in mind there are time penalties for failing exams, know what you are about when attempting Engineering Knowledge at any level. If you've done the job, if you have experience and know what you're doing, you'll pass. If you don't, you shouldn't be writing it.
