I remember
Mnemonics. They’re useful little things. Here are a few you might know…if you’re old enough. If you know these, trust me, you’re at least less than young.
- Bad booze rots our young guts but vodka goes well (the less PC version, and the one I learned, is “bad boys rape our young girls but Violet goes willingly”)
- True virgins make dull company at weddings
- Can dead men vote twice at elections

The first one is used to remember the color codes for resistors, but what are last two used for?
Very good! The last two are for remembering the order of operations for compass navigation.
Yep, any navigator would recognize the last two! Converting true to compass with variations or the reverse. Just remember to ADD East if you’re going from compass to true…
