TBAS Diagonal Orientation Question help

[Yeeyee]

Taking the TBAS next week and doing some studying, I have the orientation section down pretty good when the yellow arrow is pointing towards a cardinal direction, but I’m confused when it gets diagonal. Anyone have any info? Links to articles or videos work too. Want to get it down cold. Any other TBAS tips appreciated.

What i did was start working my way around clockwise. If the yellow arrow pointed north east i knew the first square clockwise was east, the next was south, then west, then north. It wasn't super fast but it was consistent. After practice it can be pretty quick.
