(Memory Trick) 6 Federal areas of exclusive authority
I hard a hard time memorizing this list, here's a memory trick I created to help : CABBTR
Criminal Law
Aliens & Naturalization
Banking
Bankruptcy & Insolvency
Taxation
Regulation of Trade & Commerce
This makes me think of The Cab(b)ot Trails (NS), one of the many places I plan on visiting once this exam is done

Memory hints always work better when they are personal! I'll link to your post from the wiki so others can either use yours or get inspiration to create their own! (The place I wanted most to visit after Exam 6 was my bed.
)
Hey @graham, I also find it useful to utilize AI for acronyms. For example, I rearranged this as BATCRB ("bat crib"), then I use https://creator.nightcafe.studio/ or DALL-E to use AI to generate a visualization of this, and include it in my notes.
That is fascinating! You just type in anything and it creates a picture based on what you entered! I'm putting this in my bookmarks.
(Sorry it took me so long to respond. I was busy these last few days.)
I came up with "C-RABBIT" (think it as a Canadian rabbit)
I've linked to this thread from here. Thanks!
