r/Mnemonics

I only find expensive courses

What are the best free resources? Are there any?

For example, some website where I can practice Memory palace and image link method?

I recently decided to learn all of the countries and their outline/location. I used Sporcle, Quizlet and a few other apps but I also came up with a few mnemonics and other little tricks for some and was wondering if anyone else had their own!

For example a few of mine:
NSFR - Not Safe For Russia/Norway Sweden Finland Russia
Guyana is shaped like a little guy
Uzbekistan has a little U shape cut out
Croatia has a split like the city Split
Burundi is at the Bottom of the two little countries
Niger is a fish called Nigel
Latvia is V shaped
Thailand is like a T
Yemen Oman is like something going well and then not ‘Yeah man! Oh man’
Venezuela and Lithuania kind of rhyme and kind of look similar
Mali is a backwards L

Not a foolproof one but countries with a Z in tend to be funky shapes
