If you do a lot of electronic work, it may be handy to keep a color-coded resistor chart nearby. Becky Stern of Adafruit has you covered with this cross stitch sampler. You can find her pattern at the link.
When I took CompTIA A+ in 1999 memorizing the color-coding of resistor bands was one of the requirements. This would have been handy since I'm pretty sure I got all of those questions wrong. And this was during a time when all PC parts became FRUs and knowledge of this wasn't even applicable to computer repairs anymore.
