A QMED is basically an apprentice engineer. At least thats how i looked at it. On OSV sometimes oiler or QMED you may be stuck watching a hose your whole watch so to learn you may have to put in the extra effort and stay up a hour or 2 into your off time if you want to learn. If you are good and put in that extra effort the Chief and Master will talk you up to the managers. In a few years you will have your license and already be ahead of the rest because you know how to actually hold a watch. You are still going to have to wake the Chief up from time to time but he knows that. You will learn alot and learn fast if you pay attention and put in a small amount of extra effort.
