I will finish up all of my STCW courses sometime this spring…In the mean time I am hitting the books pretty hard …I am running into a problem though…

The questions on the Navigation Problems module, that have to do with fuel consumption, New Distance with remaining fuel and change of speed etc…I haven’t had this class yet but It drives me nuts when I am taking practice tests and run across these particular questions…So I have decided to teach myself the formulas …Most of you have been through this before, is there a good way to keep them all straight.?.I mean on some of them you are using a cube root for speed but on others a square root…Any advice would be appreciated…
