there's questions about common mode interference and other RFI things, cabling, antennas, and things like that. strict "rules only" is technician - what bands, how much power (which gets interesting in quite a few bands), and so on. Technician is like "set up a modem to get on a BBS."
A good chunk of the questions are memorizing frequencies and wattages you're allowed to use for various things... something you can print off on a chart and tape to the wall.
